Question

Нужно найти токи и напряжения на всех резисторах, I1=2A

Answer 1

1/R5.6=1/R5+1/R6=1/4+1/12=4/12   R5.6=3 Ом
R4.5.6=R4+R5.6=3+3=6 Ом
1/R3.4.5.6=1/R3+1/R4.5.6=1/6+1/6=2/6   R3.4.5.6=3 Ом
1/R2.3.4.5.6=1/R2+1/R3.4.5.6=1/8+1/3=11/24  R2.3.4.5.6= 2.18 Ом
R1.2.3.4.5.6=R1+R2.3.4.5.6=9+2.18=11.18 Ом
U1=I1*R1=2*9=18 B
I1=I2.3.4.5.6=2 A
U2.3.4.5.6=I2.3.4.5.6*R2.3.4.5.6=2*2.18=4.36 B
U2.3.4.5.6=U2=U3=U4.5.6=4.36 B
I2=U2/R2=4.36/8=0.545 A
I3=U3/R3=4.36/6=0.727 A
I4.5.6=U4.5.6/R4.5.6=4.36/6=0.727 A
I4.5.6=I4=I5.6=0.727 A
U4=I4*R4=0.727*3=2.18 B
U5.6=I5.6*R5.6=0.727*3= 2.18 B
U5.6=U5=U6=2.18 B
I5=U5/R5=2.18/4=0.545 A
I6=U6/R6=2.18/12=0.182 A
