Find the current in the 3Ω resistor of the given network using Superposition principle.(a) 2.5A(b) 3.125A(c) 6.525A(d) 5.625AI had been asked this question in homework.This is a very interesting question from Maximum Power Transfer and Superposition in division Techniques of Circuit Analysis of Electric Circuits

Answer»

The correct choice is (d) 5.625A

To elaborate: 1.When 20v SOURCE acting alone: CURRENT source is REPLACED by open CIRCUIT.Req= 5+3=8Ω and Current I= 20/8=2.5A

2. When 5A source acting alone: 20v source is replaced by a short circuit. By current DIVISION rule, I3= 25/8=3.125A

Total current through I3= 2.5+3.125=5.625A.
