Question

Which, among the following is the correct expression for admittance?

(a) Y=Z

(b) Y=1/Z

(c) Y=Z^2

(d) Y=1/Z^2

This question was posed to me in semester exam.

Query is from Basic AC Parallel Circuits in chapter Single-Phase Parallel Networks of Basic Electrical Engineering

Answer 1

Correct choice is (b) Y=1/Z

Explanation: We know that admittance is the reciprocal of impedance, hence the correct expression for admittance is: Y=1/Z.
