Answer :

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

Capacitors in series:

If capacitors C1, C2, C3 , … are in series, then the equivalent capacitance is given by:

We can replace C1 and C2 by Ceq. As C1 ans C2 are in series,

Let us drop the subscript and call Ceq just C.

Let the potential across the capacitor C be at time t be Vc. Let the charge at time t be q.

Note that as C1 and C2 are in series,

Applying Kirchhoff’s loop rule ,

We know that

Where B is a constant


Substitute q = 0 at t = 0,

Substituting the value of A back,
