Question
The variation of the instantaneous current (I) and the instantaneous emf (E) in a circuit is as shown in fig. Which of the following statements is correct -
Options
A.The voltage lags behind the current by π/2
B.The voltage leads the current by π/2
C.The voltage and the current are in phase
D.The voltage leads the current by π
Solution
E reaches at maximum value at
phase before I reaches at its peak at phase π.So E is leads I by
So E is leads I by
