求开路电压Ucd。

核心提示给你个参考1)Uab = I' * (R1+R3) = I'' * (R2+R4);I' + I'' = 3A;2)Ucd = Ucb + Ubd = -I' * R1 + R2 * I'';好了,余下的你自己去解决吧UCD=UGH,此时电

给你个参考

1)Uab = I' * (R1+R3) = I'' * (R2+R4);I' + I'' = 3A;

2)Ucd = Ucb + Ubd = -I' * R1 + R2 * I'';

好了,余下的你自己去解决吧

UCD=UGH,

此时电路是(R+9R)//10R/9,并联后的电阻为1R,再串联10R,那么并联电路的分压UEF=UEH=110*R/(R+10R)=10V

UCD=UGH=10*R/(9R+R)=1V
