Question 692: Electrostats & Capacitance

Question

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

Accepted Answer

Charge Q = C
1
V
Total capacity of combination (parallel)
C = C
1
+ C
2
$$P.D. = {Q \over C} = {{{C_1}V} \over {{C_1} + {C_2}}}$$

Answer

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

Answer

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

Answer

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

Answer

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