AIPMT 2002 | Capacitor Question 34 | Physics

A capacitor of capacity C₁ charged upto V volt and then connected to an uncharged capacitor of capacity C₂. The final potential difference across each will be

$${{{C_1}V} \over {{C_1} + {C_2}}}$$

$${{{C_2}V} \over {{C_1} + {C_2}}}$$

$$\left( {1 - {{{C_2}} \over {{C_1}}}} \right)V$$

$$\left( {1 + {{{C_2}} \over {{C_1}}}} \right)$$

Energy per unit volume for a capacitor having area A and separation d kept at potential difference V is given by

$${1 \over 2}{\varepsilon _0}{{{V^2}} \over {{d^2}}}$$

$${1 \over {2{\varepsilon _0}}}{{{V^2}} \over {{d^2}}}$$

$${1 \over 2}C{V^2}$$

$${{{Q^2}} \over {2C}}.$$
