Question

Find the voltage Vab in the circuit shown above using Superposition theorem.

(a) 4∠0⁰

(b) 50∠0⁰

(c) 54∠0⁰

(d) 46∠0⁰

The question was posed to me by my school principal while I was bunking the class.

Origin of the question is Superposition Theorem in chapter Steady State AC Analysis of Network Theory

Answer 1

Right answer is (b) 50∠0⁰

To explain I would say: The total voltage is the sum of the two voltages V1 and V2 => Vab = V1+V2 = 50∠0⁰V.
