MCQ (Single Correct Answer)

-1

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

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

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

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

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