Electromagnetic Induction question

2017 · Shift 2 · Q50

JEE AdvancedPhysicsElectromagnetic InductionMultiple correct+4 / −2
A source of constant voltage V is connected to a resistance R and two ideal inductors L1 and L2 through a switch S 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/are correct? JEE Advanced 2017 Paper 2 Offline Physics - Electromagnetic Induction Question 10 English
  1. A
    After a long time, the current through L1 will be VRL2L1+L2{V \over R}{{{L_2}} \over {{L_1} + {L_2}}}RV​L1​+L2​L2​​
  2. B
    After a long time, the current through L2 will be VRL1L1+L2{V \over R}{{{L_1}} \over {{L_1} + {L_2}}}RV​L1​+L2​L1​​
  3. C
    The ratio of the currents through L1 and L2 is fixed at all times (t > 0)
  4. D
    At t = 0, the current through the resistance R is VR{V \over R}RV​
