Q. Spherical CapacitorIt consists of two concentric conducting spherical shells of radii

a

and

b (a < b)

. The inner shell is given a charge

Q

and outer shell is given a charge

Q

. The potential difference between the shells is given by

V_{i} - V_{0} = - \int_{b}^{a} E d r

\Rightarrow V = - \int_{b}^{a} \frac{Q}{4 π ε_{o} r^{2}} d r

\Rightarrow V = \frac{Q (b - a)}{4 π ε_{o} a b}

Now,

C = \frac{Q}{V} \Rightarrow C = \frac{4 π ε_{o} (a b)}{(b - a)}
