JEE MAIN - Physics (2019 - 12th January Morning Slot - No. 8)
In the figure shown, a circuit contains two identical resistors with resistance R = 5$$\Omega $$ and an inductance with L = 2mH. An ideal battery of 15 V is connected in the circuit. What will be the current through the battery long after the switch is closed ?

6 A
7.5 A
3 A
5.5 A
Explanation
Ideal inductor will behave like zero resistance long time after switch is closed

I = $${{2\varepsilon } \over R}$$ = $${{2 \times 15} \over 5} = 6A$$
I = $${{2\varepsilon } \over R}$$ = $${{2 \times 15} \over 5} = 6A$$
