Объяснение:
r12 = R1*R2 / (R1+R2) = 36*48 / (36+48) = = 20.57 Ом
r45 = R4*R5 / (R4+R5) = 24*12 / (24+12) = = 8 Ом
r345 = r45+R3 = 8+8 = 16 Ом
R = r12 * r345 / (r12 + r345) = 20.57 * 16 / (20.57 + 16) == 9 Ом
I = U/R = 144/ 9 = 16 A
I1 = U/R1 = 144 / 36 = 4 A
I2 = U / R2 = 144 / 48 = 3 A
I3 = I - I1 - I2 = 16 - 4 - 3 = 9 A
U3 = I3*R3 = 9*8 = 72 B
U4 = U5 = U-U3 = 144 - 72 = 72 B
I4 = U4 / R4 = 72 / 24 = 3 A
I5 = I3 - I4 = 9-3 = 6 A
