The ___ 1、collisions ___ produce heat, increasing the temperature of the material. Consider the ordinary toaster. Current flows through the ___2、wires ___ of the power cord and through the toaster's filament (the glowing wire you see inside). The same current must flow in the power cord as flows through the filament. The cord has very little ___ 3、resistance ___, while the filament has considerably more. Since the filament has a much higher resistance than the cord, it ___ 4、produces ___ much more heat. That's as it should be. You want the heat for your toast, but you do not want the power cord getting ___ 5、hot ___! The standard incandescent light bulb is another example. The filament in the light bulb glows white hot (hence, the word "incandescent") to produce light and a lot of heat as well. But, the low-resistance power cord stays cool.六、根据下列短文回答问题,回答请使用英文。
电气工程及其自动化专业英语答案
第一章⚫Section1习题答案一.Choose the best answer into the blank1.B2.D3.C4.A5.B二.Answer the following questions according to the text1.No. The current need not be a constant-valued function because charge can vary with2.Time.2.The current increases when the time rate of charges is greater.3.The uab=-1V can be interpreted in two ways:①point b is 1 V higher than point a;②the Potential at point a with respect to point b is -1V.4.w=∫pdt5.Because by the passive sign convention,current enters through the positive polarity ofThe voltage,p=ui>0 implies that the element is absorbing power and p=ui<0 impliesThat the element is releasing or supplying power.⚫Section2习题答案一.Choose the best answer into the blank1.B2.A3.B4.C5.B二.Answer the following questions according to the text1.The difference between an independent source and a dependent source is: the source2.Quantity of a dependent source is controlled by another voltage or current,but the source Quantity of an independent source maintains a specified value.3.An ideal independent source is an active element that provides a specified voltage or4.Current that is completely independent of other circuit variables.3.No.The current through an independent voltage source can be calculated by the4.External circuit.4.A voltage-controlled voltage source(VCVS),A current-controlled voltage source (CCVS),A voltage-controlled current source (VCCS), A current-controlled current source (CCCS)5.No,it isn’t.三.Translate the following into Chinese（译文）在随后内容中提及的所有简单电路元件，根据通过它的电流和其两端电压之间的关系进行分类。
