Question

Three capacitors of capacitances $2pF,3pF$ and $4pF$ are connected in parallel.
Determine the charge on each capacitor if the combination is connected to a $100V$ supply.

Answer 1

$C_1=2pF,C_2=3pF,C_3=4pF$

$V=100V$

Let $q_1,q_2,q_3$ be the charges on the capacitors $C_1,C_2$ and $C_3$ respectively.

potential difference $=100V$

$q_1=2\times {10}^{-10}C$ (By formula $q=CV$)

$q_2=3\times {10}^{-10}C$

$q_3=4\times {10}^{-10}C$
