Capacitors in Parallel

In the Parallel combination, the capacitors are first arranged so that all the first plates of different capacitors are connected at one terminal and all the second plates of the capacitors are connected at another terminal . The two terminals are then connected to the two terminals of a battery.

Consider two capacitors of capacitance C1 and C2 connected in parallel to a battery of potential difference V.
The charges on each capacitor is given as
Q1 = C1V and Q2 = C2 V

The total charge drawn from the battery is

Q = Q1 + Q2 = C1V + C2V.
If C is the combined capacitance of two capacitors then total charge drawn from the battery is Q = CV, the above equation changes to
CV = C1V + C2 VFor ‘n’ numbers of capacitors in parallel then combined capacitance is C = C1 + C2 + C3 ………………… + Cn.
