For the circuit shown below. The dependent source—

1. Supplies 40 W
2. Absorbs 50 W
3. Supplies 50 W
4. Absorbs 40 W

Correct Option: B

Given, l_x = 5A
Voltage at dependent source terminal is
= – 2 i_x
= – 2 × 5 = – 10V
P = V × i_x
or P = 10 × 5 = 50 W
Since current is entering in the independent source. It means power is absorbed by the dependent source.
