Question
A source of constant voltage $V$ is connected to a resistance $R$ and two ideal inductors $L_1$ and $L_2$ through a switch S as shown. There is no mutual inductance between the two inductors. The switch $S$ is intially open. At $t=0$, the switch is closed and current begins to flow. Which of the following options is/are correct?

Select ALL correct options:
A
At $t=0$, the current through the resistance $R$ is $\frac{V}{R}$
B
The ratio of the currents through $L_1$ and $L_2$ is fixed at all tmes ( $t>0$ )
C
After a long time, the current through $L_2$ will be $\frac{V}{R} \frac{L_1}{L_1+L_2}$
D
After a long time, the current through $L_1$ will be $\frac{V}{R} \frac{L_2}{L_1+L_2}$
