Capacitor C_1 of capacitance 1 μ F and capacitor C_2 of capacitance 2 μ F are separately charged fully by a common battery. The two capacitors are then separately allowed to discharged through equal resistors at time t=0

Question

Correct answer: B. the currents in the two discharging circuits at t=0 are equal but non-zero

Here, V_0 and R in the two C R circuits are same, hence the currents in the two discharging circuits at t=0 (V_0 / R) will be same. We know that, time constant of a resistance and capacitance circuit is C R . Here, time constant of first circuit (capacity C_1=1 μ F ) is half of the time constant of second circuit (capacity C_2=2 μ F ). Hence, C_1 loses 50 \% its initial charge sooner.
