R1支路电流比R2支路电流比R3支路电流=1/R1∶1/R2∶1/R3=0.067∶0.05∶0.1
I1=In×[1/R1÷﹙1/R1＋1/R2＋1/R3﹚]=In×[0.067÷﹙0.067＋0.05＋0.1﹚]
I2=In×[1/R2÷﹙1/R1＋1/R2＋1/R3﹚]=In×[0.05÷﹙0.067＋0.05＋0.1﹚]
I3=In×[1/R3÷﹙1/R1＋1/R2＋1/R3﹚]=In×[0.1÷﹙0.067＋0.05＋0.1﹚]
分流电路：I=I1+I2 I1=U/R1 I2=U/R2 I=U(1/R+1/R2)=U*(R1+R2)/R1*R2即：U=I*R1R2/(R+R2) 代入I1=U/R1 得I1=I*R2/(R1+R2 ) 将U=I*R1R2/(R+R2) 代入I2=U/R2得：I2=I*R1/(R1+R2)
分压电路：U=U1+U2 U1=I*R1 U2=I*R2 U=I(R1+R2）得I=U/(R1+R2)代入
U1=I*R1得U1=U*R1/(R1+R2)将I=U/(R1+R2)代入
U2=I*R2得U2=U*R2/(R1+R2)
