Question

In a pure inductive circuit or In an ac circuit containing inductance only, the current(a) Leads the e.m.f. by 90°
(b) Lags behind the e.m.f. by 90°
(c) Sometimes leads and sometime lags behind the e.m.f.(d) Is in phase with the e.m.f.

Answer 1

Correct Answer is d : option b

" Lags behind the e.m.f. by 90° "

explanation :

Pure inductive circuit is the circuit which contains only inductance (L) and not any other quantities like resistance and capacitance in the Circuit .

In this type of circuit, the current lags behind the voltage by an angle of 90 degrees

Answer 2

Answer:

option "b" is right....
