How many capacitors are connected in parallel to a voltage source?
In the figure given below, three capacitors C1, C2, and C3 are connected in parallel to a voltage source of potential V. Deriving the equivalent capacitance for this case is relatively simple. Note that the voltage across each capacitor is the same as that of the source since it is directly connected to the source.
