At the time t=0, e is max and is equal to E, but current i is zero. As the time passes, current through the circuit increases but induced emf decreases.

Q. Switch $S$ of the circuit, shown in figure, is closed at $t = 0$ . If $e$ denotes the induced emf in $L$ and $i$ , the current flowing through the circuit at time $t$ , which of the following graphs is correct?

At the time $t = 0, e$ is max and is equal to $E$ , but current $i$ is zero.
As the time passes, current through the circuit increases but induced emf decreases.
