Question

In a pure inductive circuit or In an ac circuit containing inductance only, the current

• A. Leads the e.m.f. by ${90}^{\circ }$
• B. Lags behind the e.m.f. by ${90}^{\circ }$
• C. Sometimes leads and sometime lags behind the e.m.f.
• D. Is in phase with the e.m.f.

Answer 1

The correct option is B Lags behind the e.m.f. by ${90}^{\circ }$

The current lags behind the e.m.f. by ${90}^{\circ }$
