Answer:
When a.c. is applied across a pure inductor,e.m.f. lags the current by π/2.
Explanation:
AC means Alternative Current.In AC,the current keeps switching directions periodically - forward and backward.
Pure conductor means perfect electrical conductor.
And EMF means Electric and Magnetic Field.
When AC is applied across a pure conductor then EMF lags the current by 90°= π/2
