Question

Find the current flowing through 5Ω resistor in the given circuit.

(a) 0.57A

(b) 0.64A

(c) 0.78A

(d) 0.89A

This question was addressed to me by my college professor while I was bunking the class.

The origin of the question is The Mesh-Current Method and Dependent Sources and Some Special Cases in section Techniques of Circuit Analysis of Electric Circuits

Answer 1

The correct option is (c) 0.78A

The explanation is: There are 3 meshes in the given circuit. Assuming currents I1, I2, I3 in the 3 meshes and by applying KVL, equations will be obtained which on solving gives the respective currents flowing in the circuits.
