Question 1-3 are based on the following passage
Hard
Solving time: 4 mins
The capacitor of capacitance can be charged (with the help of a resistance ) by a voltage source , by closing switch while keeping switch open. The capacitor can be connected in series with an inductor by closing switch and opening .
Hard
Initially, the capacitor was uncharged. Nowwitch is closed and is kept open. If time constant of this circuit is , then
Hard
After the capacitor gets fully charged, is opened and is closed so that the inductor is connected in series with the capacitor. Then,
Hard
If the total charge stored in the circuit is , then for ,
