Question

The circuit which satisfies Reciprocity Theorem is called?

(a) Short circuit

(b) Open circuit

(c) Linear circuit

(d) Non-linear circuit

The question was posed to me in an interview for internship.

The doubt is from Reciprocity Theorem in portion Useful Theorems in Circuit Analysis of Network Theory

Answer 1

Correct option is (c) Linear circuit

To explain: The circuit which satisfies Reciprocity Theorem is called linear circuit. A linear circuit is an electronic circuit in which, for a sinusoidal input voltage of frequency f, any steady-state output of the circuit (the current through any component, or the voltage between any two points) is also sinusoidal with frequency f.
