[1] In the case of a resistor, the voltage-current relationship is given by Ohm’s law, which states that the voltage across the resistor is equal to the current through the resistor multiplied by the value of the resistance.

就电阻来说，电压—电流的关系由欧姆定律决定。欧姆定律指出：电阻两端的电压等于电阻上流过的电流乘以电阻值。

Which做关系代词，以引出非限制性定语从句。

[2]It may be that the inductor voltage rather than the current is the variable of interest in the circuit.

或许在电路中，人们感兴趣的变量是电感电压而不是电感电流。

P1U2A The Operational Amplifier 运算放大器

amplifier n. 放大器

integrated circuit 集成电路

building blocks 积木

potential n. (电)势

cascade n., v. 串联；adj. 串联的

on the order of 属于同类的，约为

trade off 换取

cumbersome adj. 麻烦的

intrinsic adj. 内在的

circuitry n. 电路

[1] One problem with electronic devices corresponding to the generalized amplifiers is that the gains, AU or AI, depend upon internal properties of the two-port system.

对应于像广义放大器这样的电子装置，一个问题就是增益AU 或者AI ，它们取决于两输入端系统的内部特性。

[2] This is one of the key features of Op-Amp design—the action of the circuit on signals depends only upon the external elements which can be easily varied by the designer and which do not depend upon the detailed character of the Op-Amp itself.

这是运算放大器设计的重要特征之一——在信号作用下，电路的动作仅取决于能够容易被设计者改变的外部元件，而不取决于运算放大器本身的细节特性。

P1U3A Logical Variables and Flip-flop 逻辑变量与触发器

flip-flop n. 触发器

relevance n. 关联

terminology n. 术语

aptness n. 恰当

pilot n. 飞行员

aloft adv. 高高地

simultaneously adv. 同时地

Boolean algebra 布尔代数

gate n. 门，门电路

prevalent adj. 流行的

inhibit v. 抑制

难句翻译

[1] We shall now briefly discuss the relevance of such

terminology, and in so doing we shall bring out the

special aptness of the designations “true” and “false” to

identify the possible values of a variable.

现在我们将简要地讨论一下这些术语之间的关联，并在此过程中阐明用标示“真”和“假”来识别一个变量的可能值的特殊用途。

[2] Just as other algebras deal with variables which have a numerical significance, Boolean algebra deals with propositions and is an effective tool for analyzing the relationships between propositions which allow only two mutually exclusive alternatives.
