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

Answer»

Solution :EQUIVALENT capacitance,
`C=C_(1)+C_(2)+C_(3)=2pF+3pF+4pF=9pF`
or `C=9xx10^(-12)F`
Charge on the parallel combination of the capacitor and HENCE the charge on each capacitor,
`q=CV=9xx10^(-12)xx100=9xx10^(-10)C`.
