A capacitor C 1 of capacitance 1 μF and a capacitor C 2 of capacitance 2 μF are separately charged by a common battery for a long time. The two capacitors are then separately discharged through equal resistors. Both the discharge circuits are connected at t = 0.

Given:

Both the capacitors are connected to a same battery forma long time. So capacitors fully charged. The two capacitors connected to an equal resistors separately at t=0. Now the capacitors starts discharge at the same time. So at t=0 the current in both discharging circuits are equal but not zero. Capacitors are in the ratio 1:2. So C₁ loses 50% of its initial charge sooner than C₂ loss 50% of its initial charge.

If the charged capacitors connected to the same resistance separately then the currents in the two discharging circuits at t = 0 are equal but not zero and C₁ loses 50% of its initial charge sooner than C₂ loss 50% of its initial charge. Option B and D are correct.

A capacitor C1 of capacitance 1 μF and a capacitor C2 of capacitance 2 μF are separately charged by a common battery for a long time. The two capacitors are then separately discharged through equal resistors. Both the discharge circuits are connected at t = 0.
