Question

In an inductive circuit, the voltage_______ the current?

(a) Leads

(b) Lags

(c) Is greater than

(d) Is less than

I have been asked this question at a job interview.

This interesting question is from Mechanical Analogy, Current and Voltage in an Inductive Circuit topic in portion Single Phase Series Circuits of Basic Electrical Engineering

Answer 1

Correct choice is (a) Leads

To explain I would say: In a pure inductive circuit the voltage leads the current and the current lags the voltage by a phase difference of 90 degrees.
