Answer :

Note that and .

Concepts/Formulas used:

Kirchhoff’s loop rule:

The sum of potential differences around a closed loop is zero.


If two conductors have a potential difference V between the them and have charges Q and -Q respectively on them, then their capacitance is defined as

Let the potential across the capacitor be at time t be Vc. Let the charge at time t be q. The initial charge is Q.

Applying Kirchhoff’s loop rule ,

We know that

Using the property : , we get

Note that at any time,

Thus, we can remove the modulus,
