Question : 8 of 54

Marks: +1, -0

A source of constant voltage V is connected to a resistance R and two ideal inductors L1 and L2 through a switchS as shown. There is no mutual inductance between the two inductors. The switch S is initially open. At t = 0, the switch is closed and current begins to flow. Which of the following options is or are correct?

[JEE Adv 2017 P2]

At t = 0, the current through the resistance R is
V
R
After a long time, the current through L2 will be
V
R
L1
L1+L2
After a long time, the current through L1 will be
V
R
L2
L1+L2
The ratio of the currents through L1 and L2 is fixed all times (t>0)
