स्रोत से ली गई धारा है:

I=I1+I2

I=VZ1+VZ2

गणना

दिया गया है, Z1 = (4 + j3) Ω

Z2 = (3 - j4) Ω;

I=10004+j3+10003j4

I=2036.86+2053.13

I = 20 (0.8 - j0.6) + 20 (0.6 + j0.8)

I = 20 (0.8 + 0.6 - j0.6 + j0.8)

I = 20 (1.4 + j0.2)

I = 28 + j 4

I = 28.28 A

28.28 A के सबसे करीबी विकल्प विकल्प 4 है।
