Capacitors which all are connected to the same source of potential.
A
Capacitors
B
Capacitance
C
Capacitance in Parallel
D
Capacitance in Series
Explanation: 

Detailed explanation-1: -When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors’ capacitances. If two or more capacitors are connected in parallel, the overall effect is that of a single equivalent capacitor having the sum total of the plate areas of the individual capacitors.

Detailed explanation-2: -When capacitors are connected in parallel, the potential difference V across each is the same and the charge on C1, C2 is different i.e., Q1 and Q2. The charges on capacitors is given as: Q 1 = C 1 C 1 + C 2 Q.

Detailed explanation-3: -Key points of the parallel combination of capacitors The potential across each capacitor is the same in the parallel combination of capacitors. The charge is proportional to the capacitor’s capacity and is different in each case.

Detailed explanation-4: -Capacitors in Parallel If two or more capacitors are joined together in parallel, then each capacitor is connected independently to the same voltage source, which is often a battery. This means that each capacitor has the same voltage across its plates.
