are charged in parallel to the same potential difference V V by a battery. The switch is opened, so capacitors are discharged through a resistor. I wanted to know how the p.d V1 V 1 and V2 V 2 of the two capacitors would vary, with respect to time.

What is the time constant of a parallel capacitor?

The capacitors are in parallel so the potential difference across them must be the same. The time constant of the circuit should have been R(C1 +C2) R ( C 1 + C 2) as the two capacitors in parallel are equivalent to one capacitor with a capacitance equal to the sum of the capacitances of the individual capacitors.

What is total capacitance of a parallel circuit?

When 4, 5, 6 or even more capacitors are connected together the total capacitance of the circuit CT would still be the sum of all the individual capacitors added together and as we know now, the total capacitance of a parallel circuit is always greater than the highest value capacitor.

What if the capacitance of two capacitors were the same?

Unless the capacitance of the two capacitors were the same the currents I1 I 1 and I2 I 2 should not have been the same. You would expect the capacitor with the larger capacitance to have a larger discharge current because for a given voltage it store more charge.
