串连电路中的电压和电流算法 大家给个公式
串联电路中电流处处相等,关于电压,如果串联元件全是电阻性元件,那么每个元件上的电压等于电流和其电阻的乘积,如果已知总电压,那么每个元件上的电压和其电阻的大小成正比,和串联电路的总电阻成反比.例如有三个元件R1、R2、R3串联,串联电路的总电压为V,电流为I,其中各元件的分压为Vr1=I×R1,Vr2=I×R2,Vr3=I×R3,或者Vr1=V×R1/(R1+R2+R3),Vr2=V×R2/(R1+R2+R3),Vr3=V×R3/(R1+R2+R3).

电流处处相同 I=U总/R总
电压U=IR

串联电路电流处处相等 根据欧姆定律I=U/R 当你知道 电源电压 总电阻 套公式就可以算出电流大小
