Odpowiedź :

1)   Rz = R2 + R1 = 2 + 2 = 4 Ω            I = I1 = I2 = U/Rz = 36/4 = 9 A

2)  1/Rz = 1/R21 + 1/R3 + 1/R4

1/Rz = 1/4 + 1/2 + 1/4 = 4/4 = 1    --->     Rz = 1 Ω

I = U/Rz = 36/1 = 36 A

I1 = I2 = U/R21 = 36/4 = 9 A

I3 = U/R3 = 36/2 = 18 A

I4 = U/R4 = 36/4 = 9 A

3)  R312 = R3 + R1 + R2 = 2 +2 + 2 = 6 Ω

1/R3124 = 1/R312 + 1/R4 = 1/6 + 1/4 = 2/12 + 3/12 = 5/12     --->    R3124 = 12/5 Ω

Rz = R6 + R3124 + R5 = 4 + 12/5 + 4 = 20/5 + 12/5 + 20/5 = 52/5 Ω = 10.4 Ω

I = I6 = I5 = U/Rz = 36/10.4 = 3.46 A

U6 = U5 = 3.46·4 = 13.84 V          U3124 = 36 - 2·13.84 = 8.32 V

I3 = I1 = I2 = U3124/R312 = 8.32/6 = 1.38 A

I4 = U3124/R4 = 8.32/4 = 2.08 A
