For the circuit shown below, the power absorbed by 2Ω

Home » Network Theory » Network theory miscellaneous » Question

For the circuit shown below, the power absorbed by 2Ω resistor and power delivered by 10V source will be—

1. 2W, 10W
2. – 2W, 10W
3. 2W, – 10W
4. – 2W, – 10W

Correct Option: C

The given circuit:

From figure, 20 – 2I – 8 I – 10 = 0
or
I = 1A
Power absorbed by 2Ω resistor = I²R = 1² × 2 = 2W
Power delivered by 10V source = – VI = – 10 × 1 = – 10W
[Note: Here negative sign is taken because current is entering at the negative terminal of the 10V voltage source]
Hence alternative (C) is the correct choice.
