An inductor L and a resistance R are connected in series with a battery of emf E and a switch. Initially the switch is open. The switch is closed at an instant t = 0. Select the correct alternatives

A

At t = 0, induced emf in inductor is zero

B

At `t=(L)/(R)`, energy stored in the inductor is `(1-(1)/(e))^(2)((LE^(2))/(2R^(2)))`

C

At `t=(L)/(R)`, induced emf in the inductor is `(E)/(e)`

D

At `t=(L)/(R)`, voltage drop across the resistor is `E(1-(1)/(2))`
