# A capacitor C<sub A. The current in each of the two discharging circuits is zero at t = 0.

B. The currents in the two discharging circuits at t = 0 are equal but not zero.

C. The currents in the two discharging circuits at t = 0 are unequal.

D. C_{1} loses 50% of its initial charge sooner than C_{2} loss 50% of its initial charge.

Answer :

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 C_{1} loses 50% of its initial charge sooner than C_{2} 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 C_{1} loses 50% of its initial charge sooner than C_{2} loss 50% of its initial charge. Option B and D are correct.
