Find the power (W) supplied by the voltage source in the following figure.(a) 0(b) 1(c) 2(d) 3The question was posed to me at a job interview.My question comes from Supermesh Analysis in division Methods of Analyzing Circuits of Network Theory

Answer»

Correct ANSWER is (a) 0

The best EXPLANATION: I3-I2=2. As I2=-2A,I3=0A. TH term power is the product of voltage and current. So, power SUPPLIED by source = 10×0=0W.
