There are three kinds of circuits:the series circuit,the parallel circuit,and the series-parallel circuit .They are shown in fig.1 In a circuit,each of the parts has some resistance:the electrical source or the signal generator,the connecting conductors connecting conductors,and the apparatus itself.Thus,if every part has some resistance,no matter how small,there must be a voltage drop on it when the current is flowing through.This voltage drop is equal to the product of the current and the resistance,hence it is called the IR drop.And this is also called Ohm's law.A basic circuit is shown in fig.2The voltage drop on the resistance is:U=IR.Here,I means the current,and R means the resistance,and U is the voltage drop.
有三种电路的串联电路,并联电路,和串并联电路.他们被显示在图1中的电路,每个部分有一些抵抗:电光源或信号发生器,连接导体的连接导体,以及装置本身.因此,如果每一部分都有电阻,不管多么小,必须有一个电压下降时,电流流过.这压降等于产品的电流和电阻,因此它被称为压降.这也被称为欧姆定律.一个基本电路显示在fig.2the电压降电阻:你=ir.here,我是指当前,和手段抵抗,你是电压降.
