Дано: R1 = 8 Ом, R2 = 15 Ом, R3 = 10 Ом, R4 = 15 Ом, R5 = 5 Ом, U = 100 В.
R4,5 =15 + 5 = 20 Ом.
R2,3 = (15*10)/(15 + 10) = 150/25 = 6 Ом.
R1,2,3 = 8 + 6 = 14 Ом.
Rэкв = R1,2,3,4,5 = (14*20) / (14 + 20) = 280/34 = 140/17 Ом.
Iобщ = 100 / (140/17) = (170 / 14) A.
I4 = I5 = 100 / 20 = 5 A.
I1 = (100 / 14) A.
U1 = 8*(100/14) = 800/14 = (400/7) B,
U2,3 = 100 - (400/7) = (300/7) B.
I2 = (300/7)/15 = (20/7) A.
I3 = (300/7)/10 = (30/7) A.
