1.	The variation of the instantaneous current `(I)` and the instantaneous e.m.f `(E)` in a circuit is as shown in figure. Which of the following statement is correct? A. The voltage lags behind the current by `pi//2`B. The voltage leads the current by `pi//2`C. The voltage and the current are in phaseD. The voltage leads the current by `pi`
Answer» Correct Answer - B At `t=0`, phase of the voltage is zero, while phase of the current is `-(pi)/2` i.e, voltage leads by `(pi)/2`
