Объяснение:
I6=I5 = 0.6A
U6 = I6*R6 = 0.6*100 = 60 B
U5 = I5*R5 = 0.6*160 = 96 B
U65 = U34 = U6+U5 = 60+96 = 156 B
r34 = R3+R4 = 100+160 = 260 Ом
I3 = I4 = U65/r34 = 156 / 260 = 0.6A
I7 = I3+I6 = 0.6+0.6 = 1.2 A
U7 = I7*R7 = 1.2*50 = 60 B
U2 = U65+U7 = 156+60 = 216 B
I2 = U2/R2 = 216/90 = 2.4 A
I = I1 = I2 + I7 = 2.4+1.2 = 3.6 A
U1 = I*R1 = 3.6*30 = 108 B
U = U1+U2 = 108+216 = 324 B
R = U/I = 324/3.6 = 90 Ом
