4.1 Fields , Circuits And Circuit Parameters

Potential and Potential Difference

Electric charge is as fundamental a constituent of our Universe as the mass and energy.Indeed ,present physical theory supposes that all matter consists of particles ,the principal attributes of which are mass and electric charge.4.1場(chǎng)，電路和電路參數(shù)

勢(shì)和電位差

電荷是基本的組成為我們的宇宙物質(zhì)和能量。事實(shí)上，目前的物理理論假設(shè)，所有的物質(zhì)粒子組成，其中的主要屬性是質(zhì)量和電荷。

Two kinds of charge are know ,arbitrarily designated positive and negative ,which are characterized by the experimental observation that ,understatic conditions ,separated like charges exert a mutual force of repulsion ,whilst unlike charges ,under similar conditions ,exert a force of attraction.Under these conditions the field of force associated with charge is referred to as an electric field

兩種已知的，被任意指定為正和負(fù)的電荷，通過(guò)實(shí)驗(yàn)觀察表現(xiàn)出的特征是，它們?cè)陟o態(tài)條件下，分開的同類電荷受到一個(gè)相互排斥的作用力，同時(shí)，不同類的電荷，在相同條件下，受到一個(gè)吸引的作用力。在這種情況下，與電荷有關(guān)的力場(chǎng)被稱為電場(chǎng)。

The smallest known charge is that of a single electron, and, since this is much too small to adopt as a unit for all but a few special purposes ,a unit, the COULOMB, equal to 6.24*electrons ,has been chosen as the practiced(S.I.)unit.已知最小的電荷是單電子，因?yàn)閱坞娮犹×硕徊捎盟鳛橐粋€(gè)單位，除了個(gè)別特殊的目的外。所以引用了另一個(gè)單位庫(kù)倫，一庫(kù)倫等于6.24*個(gè)電子。被選為國(guó)際標(biāo)準(zhǔn)單位(SI)。

the magnitude of which is dependent upon the charges and their relative positions.As a consequence of their mutual forces, any system of charges possesses potential energy, since ,unless constrained ,the individual charges will move and energy will be released.As part of the theoretical structure this energy is ascribed to the electric field, and so it is possible to identify with every point in the field a level of energy

電場(chǎng)力大小取決于電荷之間他們的相對(duì)位置。因?yàn)槭撬鼈兿嗷プ饔昧Φ慕Y(jié)果，任何有電荷的系統(tǒng)都存在電勢(shì)量，因?yàn)椋绻麤]有約束，自由電荷將移動(dòng)和釋放能量。作為理論結(jié)構(gòu)的一部分，這種能量歸因于電場(chǎng)。因此可以確定電場(chǎng)中每個(gè)點(diǎn)的能量大小。

When one of the charges is of unit magnitude ,and positive, the energy at the point defining its position is referred to as the POTENTIAL at that point ,and hence is measured(in S.I.units)in JOULES per COULOMB(J/C)or VOLTS.The POENTIAL DIFFERENCE between two points in a field is therefore the difference in energy ,per unit charge, at the two points.一個(gè)單位正電荷，在其定義的位置的能量稱為在這點(diǎn)的電勢(shì)，因此測(cè)量時(shí)用（在國(guó)際單位）焦耳每庫(kù)倫或伏特。因此在電場(chǎng)中兩點(diǎn)之間的電勢(shì)差是指這兩點(diǎn)每單位電荷的能量

Observation shows that the force experienced by a charge—measure of the electric field strength—arise with distance and diminishes to zero only at an infinite distance from the source charge(s).Therefore a point at infinity may be considered to be at zero potential.觀測(cè)表明，通過(guò)測(cè)量電場(chǎng)強(qiáng)度的電荷的力隨著距離產(chǎn)生然后只在距離源電荷無(wú)窮遠(yuǎn)處減少到零。因此認(rèn)為在無(wú)窮遠(yuǎn)處的點(diǎn)為零電勢(shì)。

In practice, however, we are generally concerned with a datum of potential which is not zero—the most common being the earth’s surface considered as an equipotential.Since most of our experiment are earth-bound there is no need to take into account the potential of the earth with respect to the true zero datum.然而，在現(xiàn)實(shí)中，我們研究的對(duì)象通常不是零勢(shì)點(diǎn)，而最常見的是以地球表面作為等勢(shì)面參考。因?yàn)槲覀兊拇蠖鄶?shù)實(shí)驗(yàn)是地球上沒有必要考慮地球的電勢(shì)是否是真正的零電勢(shì)。

The negative sign means that energy is required from an external source to move the charge from A to B.This energy is recoverable when the charge moves from B to A.Point B is said to be at a higher potential than point負(fù)號(hào)的意思是外部的能量移動(dòng)電荷發(fā)從a到b所做的功。單電荷從b移動(dòng)到a的時(shí)候這種能量是可恢復(fù)的。那么就說(shuō)b是一個(gè)高電勢(shì)點(diǎn)。

Note that, since energy is scalar, it is not necessary to know the path followed by the charge in passing from A to

B(or from B to A)nor the law of variation of force with distance over this range.注意，因?yàn)槟茉词菢?biāo)量，它不需要知道電荷是從A到B的路徑（或從B到A的路徑）和在這個(gè)范圍內(nèi)力的的變化規(guī)律。

If ,however, the data were in terms of force at each point of the field, this potential difference would be given by integrating the scalar product of the force(per unit charge)and displacement vectors over the distance AB: 然而，如果數(shù)據(jù)是根據(jù)電場(chǎng)中每一點(diǎn)處的力，那么電勢(shì)差用ab的距離與單位電荷所受電場(chǎng)力的標(biāo)量積來(lái)表示。

Electric Current

When a charge is in motion relative to a “fixed” frame of reference, an additional force appears to an observer(equipped with a suitable detector)in the fixed frame, this force being referred to as a magnetic force.Analogously, the region of magnetic influence associated with the moving charge is called a magnetic field, because it has similar characteristics to the field of force of a magnet.It is usual to refer to moving charge by the term ELETRIC CURRENT, the intensity（強(qiáng)度）of which is equal to the time rate of charge transference between two points in a field.電流

當(dāng)電荷相對(duì)于“固定”的參照物移動(dòng)，會(huì)在固定參照物的觀察儀器上產(chǎn)生另一種力（用適當(dāng)?shù)臋z測(cè)器），這個(gè)力被叫為電磁力。類似地，由運(yùn)動(dòng)電荷產(chǎn)生磁作用的區(qū)域被稱為磁場(chǎng)，因?yàn)樗c磁力場(chǎng)有類似的特征。術(shù)語(yǔ)電流通常是指運(yùn)動(dòng)的電荷，其強(qiáng)度等于電場(chǎng)中兩個(gè)點(diǎn)間的單位時(shí)間內(nèi)所通過(guò)的電荷。

In consequence, the relation connecting charge and current is:i(t)=dq/dt, where i=current ,and q=charge.因此，電荷與電流的關(guān)系為：i(t)=dq/dt,，其中i 指電流，和q指電荷

Unit current, therefore, flows when charge is transferred at the rate of 1 COULOMB/sec, i.e.6.24*electronic charges/sec, this current being designated 1 ampere(1A).It is important to appreciate, however, that when a current be from A to B it is not necessary for every individual charge to move the whole distance AB, but only that the average rate of charge transference should conform to equation i(t).。

因此，單位電流是指電荷以1庫(kù)倫每秒即6.24*10的18次方個(gè)電子每秒進(jìn)行移動(dòng)，這個(gè)電流稱為1「安培」

（A）。而且，這很好的去說(shuō)明了，當(dāng)電流從a流到b時(shí)并不需要每個(gè)自由電子去從a一直移動(dòng)到b整段距離，而是只需要考慮電荷移動(dòng)的平均速度，就能構(gòu)造i（t）的方程。

The Electric Circuit

These and an other aspects of stationary.moving and accelerating charges are truly encompassed by Maxwell’s electromagnetic theory, but accepting certain restrictions, it is possible to apply a much simplified theory which is sufficiently accurate to describe a wide range of electrical phenomena and applications.Such a theory is referred to as CIRCUIT THEORY and is concerned with the transmission of energy from one point to another through the use of real devices such as generators wires, batteries, motors and transformers.電子電路

在這些固定的方面。麥克斯韋電磁理論是講關(guān)于加速移動(dòng)的電子理論，雖有一定的限制。但可應(yīng)用于比較簡(jiǎn)單的實(shí)驗(yàn)的理論。足夠準(zhǔn)確的描述廣泛的電現(xiàn)象和應(yīng)用。這個(gè)理論被作為對(duì)電路理論和一個(gè)點(diǎn)到另一個(gè)

點(diǎn)能量傳輸而言的標(biāo)準(zhǔn)理論。例如電機(jī)電線，電池，馬達(dá)和變壓器。

In this process, interest is focused less upon electric and magnetic fields than upon their circuit equivalents, potentialdifferences and currents.As the above section indicates, the field and circuit concepts are inseparably related, so it is a matter for philosophical argument whether energy transfer is effected by fields or by voltages and currents.Nevertheless, the usefulness of the circuit concept lies in the relatively simple solution of such problems which it permits.在這個(gè)過(guò)程中，主要集中電場(chǎng)和磁場(chǎng)和他們電路的電位差電流有密切的關(guān)系，正如上面所說(shuō)，電場(chǎng)與電路是密不可分的。能量的轉(zhuǎn)換是通過(guò)電場(chǎng)改變電壓，電流而改變的。這是一個(gè)科學(xué)的觀點(diǎn)也存在問(wèn)題他只適用于簡(jiǎn)單的電路。

The transformation from field to circuit conceptualization consists in regarding currents as flowing from one physical device to another only through wires, which connect them together, and the characteristics of each device as being purely local;that is to say, the currents may be constant or time-dependent but not dependent on space coordinates in the circuit.Such a circuit is said to consist of lumped(rather than distributed)elements, and the restriction imply that only conduction currents are considered and that displacement currents are not.從現(xiàn)場(chǎng)的概念轉(zhuǎn)化為電路中包括關(guān)于為流動(dòng)從一臺(tái)物理設(shè)備到另一只通過(guò)導(dǎo)線，電流，連接在一起，并作為being純粹的每個(gè)設(shè)備的local characteristics，這是對(duì)say，may be的currents常數(shù)或時(shí)間依賴性，但不依賴于空間坐標(biāo)的電路。這種電路可分為集中（而不是分散）等元素的限制意味著，只有傳導(dǎo)電流，位移電流考慮是不是。

Conduction currents flow particularly easily in most metals, this property being due to the extremely large number of free electrons available as charge carriers in the crystal lattice.Thus, at normal temperatures, silver is the best of all conductors, with copper and aluminum only slightly inferior.傳導(dǎo)電流的流動(dòng)，特別是在大多數(shù)金屬容易，此屬性是由于自由電子在晶格中電荷的數(shù)量極其龐大的。因此，在正常溫度下，銀是最好的所有導(dǎo)體，與只有稍差的銅和鋁。

Drift velocity is, under normal conditions of temperature, a much larger but random thermal agitation velocity which, since it does not contribute to the net transference of charge, is of no concern in the macroscopic view of current adopted here.The essential part of an electric circuit consists in its simplest form, of an energy source and an interconnected energy dissipation or conversion device, known as the load.漂移速度是，在正常條件下的溫度，一個(gè)更大的，但隨機(jī)熱攪拌速度，因?yàn)樗鼪]有貢獻(xiàn)的凈轉(zhuǎn)移的電荷，是不關(guān)心在這里通過(guò)的電流的宏觀圖。的電路的主要部分的包括在其最簡(jiǎn)單的形式中，能量源和一個(gè)相互關(guān)聯(lián)的能量耗散或轉(zhuǎn)換裝置的，被稱為負(fù)載。

practical energy source may take one of many Energy Source

A forms, depending, for example, on electro-chemical, electromagnetic, thermo-electric, photo-electric, etc.., principle, but for the purpose of circuit analysis only two idealized form are recognized, to one of which all practical sources approximate.These are: 1 the voltage source and 2 the current source.實(shí)際的能源來(lái)源可以采取許多能源來(lái)源之一

一個(gè)形式，這取決于例如，在電化學(xué)，電磁，熱，電，光電等。，原則，但對(duì)于只有兩個(gè)電路分析的目的是公認(rèn)的理想形式，其中之一便是一切可行的來(lái)源近似。它們是：1，電壓源和電流源2。

The voltage source maintains a constant terminal voltage irrespective of the current supplied to the load.It is important to appreciate that the voltage may be afunction of, for example, time, temperature, pressure, etc.;it is constant only with respect to variations of load.電壓源的端電壓保持恒定的，不論對(duì)當(dāng)前提供給負(fù)載。重要的是要明白，電壓可能是一個(gè)函數(shù)關(guān)于，例如，時(shí)間，溫度，壓力等，它是恒定的只考慮負(fù)載的變化。

The current source maintains a constant current in the load irrespective of the terminal voltage-which, in the case, is determined by the magnitude of the load.As with the voltage source, the generated current may depend on many other factors, but its one essential attribute is its independence of load.電流源保持恒定的電流在負(fù)載里，不論末端電壓如何，既然這樣，是由負(fù)載的大小決定的。與電壓源一樣，生成的電流可能取決于其他許多因素，但其本質(zhì)屬性是它獨(dú)立負(fù)載。

Power and Energy

The definitions of potential and potential difference lead to the following relationships: the energy, w, expanded in moving a charge q through a potential difference(p.d.)v is given by: w= qv, hence,dw/dt=v*dq/dt=vi.The rate of expenditure of energy is define as the power p.Hence, in general the power is givens by p(t)=v(t)*i(t)and is measured in WATTS when v and I are in volts and amperes, respectively.If power p(t)is expended for time T, the total energy expended(or stored)is :

電力和能源

潛在的定義和潛在的差異導(dǎo)致的以下幾個(gè)關(guān)系：能源，功，動(dòng)議通過(guò)電位差（PD）的V是給予一個(gè)電荷q擴(kuò)大為：w= qv，因此，dw/dt=v*dq/dt=vi。

對(duì)能量消耗率定義為權(quán)力頁(yè)因此，在一般的權(quán)力是由P吉文斯（噸）=五（噸）*我（噸），并以瓦時(shí)測(cè)v和我為伏特和安培，分別。

如果功率P（t）是為時(shí)間T，總能量消耗（或存儲(chǔ)）花費(fèi)是：

The load

By a method similar to that adopted for energy sources, the load-or passive element of a circuit---may be idealized and defined by its terminal voltage/current relationship.All practical passive devices possess energy dissipative properties, often accompanied by energy-storage properties so that three distinct idealized types are possible.負(fù)載

通過(guò)類似的方法，對(duì)能源通過(guò)負(fù)載或電路---可能是理想化，其端點(diǎn)電壓/電流關(guān)系因素。所有實(shí)際的被動(dòng)設(shè)備具有能量耗散屬性,常伴有儲(chǔ)能屬性,這樣三個(gè)不同的理想化的類型是可能的。

1.The resistance parameter

A circuit which dissipates energy but stores none is said to consist solely of resistance.The property is defined by the relationship: R=v(t)/i(t), where R is the resistance in OHMS if v(t)and i(t)are volts and amperes, respectively, and this equation is known as Ohm’s Law.1，電阻參數(shù)

一個(gè)電路只消耗能量而不儲(chǔ)存能量，那只含有電阻。該屬性由關(guān)系式R=v(t)/i(t)定義的，如果V（t）和i（t）的單位分別是伏特和安培，那么R的單位為歐姆，這個(gè)公式被稱為歐姆定律。

The corresponding diagrammatic representation is shown in Figure 4.2(a)which also shows the positive directions of p.d.and current.It should be noted that, unlike an active element, a passive element develops a potential difference in opposition to the current flow so that there is a fall of potential through the element in the direction of the current flow.相應(yīng)的圖解見圖4.2（1）該表注明了電流和電勢(shì)差的正方向。應(yīng)當(dāng)指出的是，不同于有源元件，無(wú)源元件是與電流流向相反產(chǎn)生電位差的，使得無(wú)源元件中電勢(shì)是隨著電流的流向逐降低的。

For this reason the terminal p.d.is called a potential drop or voltage drop.The element which possesses resistance is termed is a resistor.由于這個(gè)原因，端電壓稱為一個(gè)電勢(shì)的下降或電壓下降。具有電阻的元件被稱為是一個(gè)電阻器。

The reciprocal of resistance is conductance designated by the symbol G.Thus, G=1/R, the units of G being siemens, or reciprocal ohms.Hence, an alternative form of Ohm’s Law is: i(t)=v(t)G.電阻的倒數(shù)為電導(dǎo)，用符號(hào)G的表示，因此，G=1 / R，G的單位是西門子，或歐姆的倒數(shù)。因此，另一種形式的歐姆定律是：I（T）= V（T）G

The Power dissipated, v(t)i(t),may be written in terms of resistance(or conductance)and voltage or current only;thus,因此，功率，v(t)i(t)，也可以只用電流或者電壓中一個(gè)來(lái)和由電阻（電導(dǎo)）組合表示.：

2.The Inductance Parameter

A circuit is said to possess inductance if it is able to store magnetic field energy.The property is defined by the relationship v(t)=L*di(t)/d(t), where L is the inductance, the units of which are HENRYS if v and I are in volts and amperes, respectively, and t is in seconds.A p.d.of 1 V will, therefore, cause the current to change at the rate of 1 A/sec in an inductance of 1H.The circuit representation of the inductance parameter is shown in Figure 4.2(b).2，電感參數(shù)

如果一個(gè)電路是能夠存儲(chǔ)磁場(chǎng)能量，則這個(gè)電路是感性電路。該性質(zhì)是由v(t)=L*di(t)/d(t)定義的，其中L是電感，單位是亨利,電壓的單位是伏特,電流的單位是安培，時(shí)間單位是秒。因此，1 V可導(dǎo)致電流變化率1A / 1秒的1H電感。該電感參數(shù)電路如圖所示代表4.2（b）項(xiàng)。

Equation may also be written in general integral form:

The element which possesses inductance is termed an inductor.And the power, v(t)i(t), may be writen: p(t)=L*I(t)*di(t)/dt, and is non-zero only when di(t)/dt has a value.Hence for a steady current i(t)=I, p(t)=0, but for the current I to have been established, p(t)has contributed to the stored energy:where T is the time taken for the current to build up to I.公式也可以寫成一般積分形式：

擁有的元素被稱為電感的電感。

功率，電壓電流，可寫：p(t)=L*I(t)*di(t)/dt,，di(t)/dt不等于零，有一個(gè)值。因此，對(duì)于一個(gè)穩(wěn)定的電流i（t）=I，p(t)=0，但對(duì)目前我已經(jīng)確定，功率有助于儲(chǔ)存能量，其中T是所用的時(shí)間，I是電流。

3.The capacitance parameter 3。電容參數(shù)

A circuit which is able to store electrostatic field energy is said to possess capacitance.The property is defined in terms of the electric charge stored per unit of potential difference at its terminals, according to the equation: q(t)=Cv(t), where C is the capacitance, the units of which are FARADS when v and q are in volts and coulombs, respectively.Hence, a capacitance of 1 F stores a charge of 1C for a terminal p.d.of 1V.Combining equations gives: I(t)=C dv(t)/dt with t in seconds.一個(gè)電路能夠存儲(chǔ)靜電場(chǎng)能量便是具有容性。性質(zhì)由其端子在電荷存儲(chǔ)每單位電勢(shì)定義的，其根據(jù)公式：q(t)=Cv(t)，當(dāng)v和Q分別是伏特和庫(kù)時(shí)，其中C是電容，單位是法拉。因此，一個(gè)1F電容存儲(chǔ)1C的電荷時(shí)末端電勢(shì)1V。結(jié)合方程可得：I(t)=C dv(t)/dt，時(shí)間電位是秒。

Thus, a current of 1A flows into a capacitance of 1 F when the terminal voltage changes at the rate of 1V/sec.因此，1A電流流入1 F的電容時(shí)，端電壓變化率為1V/sec。

And the equation may be rewritten in general integral form :

而方程可重寫為一般積分形式：

The element which possesses capacitance is termed a capacitor, and its circuit representation is illustrated in Figure 4.2.(c).該元素具有電容被稱為一個(gè)電容器，其電路圖說(shuō)明如圖4.2。

The power,v(t)i(t), may be written: p(t)=C*v(t)*dv(t)/dt and is non-zero only when dv(t)/dt has a value.Hence, for a steady voltage v(t)=V, say, p(t)=0,but for the voltage V to have built up on the capacitor, p(t)has contributed to the stored energy,where T is the time taken for the voltage to have built up to V.功率，v(t)i(t)，可寫為：p(t)=C*v(t)*dv(t)/dt，當(dāng)dv(t)/dt不等于零時(shí)才有意義。因此，對(duì)于一個(gè)穩(wěn)定電壓v(t)=V，表示p(t)=0，但對(duì)有電壓V的電容器，功率有助于儲(chǔ)存能量，其中T是所用的時(shí)間，V是電壓。

Equations v(t)= L*di(t)/dt and I(t)=C*dv(t)/dt show that step discontinuities are not possible in the current through inductance nor in the voltage across capacitance, since such steps would require, respectively, infinite voltage and infinite current.The ideas implicit in these restrictions are important in the analysis of circuits containing inductance and capacitance since they enable the initial conditions to be defined.方程v(t)= L*di(t)/dt和I(t)=C*dv(t)/dt顯示，步驟不連續(xù)電流是不可能通過(guò)電感或電壓儲(chǔ)在電容，由于這樣的步驟分別需要無(wú)限大的電壓和無(wú)限大的電流。在這限制的條件下，對(duì)電感和電容的電路的分析是重要的，因?yàn)檫@是定義它們的初始條件

歐姆定律

Ohm’s law states that the voltage across the resistor is equal to the current through the resistor multiplied by the value of the resistance.法拉第定律

Faraday’s states that the voltage across the inductor is proportional to the rate of change with time of the current through the inductor.基爾霍夫第一定律

Kirchhoff’s first law states that the algebraic sum of the voltages around a closed loop is 0,or,in any closed loop, sum of the voltage rises must equal the sum of voltage drops.運(yùn)放

The first law states that in normal op-amp circuits we may assume that the voltage difference between the input terminals is zero, that is, U+=U-.The second law states that in normal op-amp circuits both of the input currents may be assumed to be zero: I+=I-電路理論 theory of circuit
