Question

The current I in an A.C. circuit inductance coil varies with time according to the graph given below. Which one of the following graphs gives the variation of voltage with time? (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

In an A.C. circuit with inductance coil, the
voltage V leads the current / by a phase difference
of 90

^{\circ}

. Or the current I lags behind the voltage V
by a phase difference of 90

^{\circ}

. Thus the voltage goes
on decreasing with the increase in time as shown
in the graph (a).
