Question

Метод эквивалентных преобразований

Answer 1

R12=R1*R2/(R1+R2)=1*2/(1+2)=0.67 Ом

R56=R5*R6/(R5+R6)=5*6/(5+6)=2.73 Ом

R12356=R12+R3+R56=0.67+3+2.73=6.4 Ом

Ro=R12356*R4/(R12356+R4)=6.4*4/(6.4+4)=2.46 Ом

Io=U/Ro=10/2.46=4.07 A

I4=U/Ro=10/4=2.5 A

I3=Io-I4=4.07-2.5=1.57 A

U3=I3*R3=1.57*3=4.71 B
