Find the power delivered by the voltage source in the network given below.(a) 65Watts(b) 72Watts(c) 63Watts(d) 76WattsThe question was asked in an international level competition.I'm obligated to ask this question of The Mesh-Current Method and Dependent Sources and Some Special Cases topic in chapter Techniques of Circuit Analysis of Electric Circuits

Answer»

The correct option is (C) 63Watts

Best explanation: 3 loops and a supermesh between loop1 and loop3. Using KVL CURRENTS are FOUND out. I1=9A, I2=2.5A, I3=2A. As voltage source is in 1st loop, Power DELIVERED by voltage source=V*I1.
