найдем эквиваленты сопротивлений
r34 = R3+R4 = 6+4 = 10 Ом
r346 = R6*r34 / (R6+r34) = 15*10 / (15+10) = 6 Ом
r 3465 = r346 + R5 = 6+4 = 10 Ом
r13465 = R1*r3465 / (R1 + r3465) = 15*10 / (15+10) = 6 Ом
I2 = U1 / r13465 = 36 / 6 = 6 A
U2 = I2*R2 = 6 * 4 = 24 B
Uна зажимах = U1+U2 = 36+24 = 60 B
I1 = U1 / R1 = 36 / 15 = 2.4 A
I6 = U1 / r3465 = 36 / 10 = 3.6 A
U6 = I6*R6 = 3.6 * 4 = 14.4 B
U5 = U1-U6 = 36 - 14.4 = 21.6 B
I5 = U5 / R5 = 21.6 / 15 = 1.44 A
I3 = I4 = U5 / r34 = 21.6 / 10 = 2.16 A
