JEE Advanced 2016 Physics question
Two inductors (inductance 1 mH, internal resistance 3 ) and (inductance 2 mH, internal resistance 4 ), and a resistor (resistance 12 ) are all connected in parallel across a 5 V battery. The circuit is switched on at time . The ratio of the maximum to the minimum current () drawn from the battery is
Answer: 8
Solution
At the inductors oppose any sudden current, so current flows only through : A. After a long time the inductors behave as their internal resistances, so , and are in
