Question

Superposition theorem is valid for only linear systems.

(a) true

(b) false

The question was posed to me during an online interview.

Question is taken from Superposition Theorem in division Steady State AC Analysis of Network Theory

Answer 1

Correct answer is (a) true

To explain I would say: Superposition theorem is valid for only linear systems. Superposition theorem is not valid for non-linear systems. In a network containing complex impedance, all quantities must be treated as complex numbers.
