Combination of Capacitor—

Capacitor are combined in two manner

1. Series Combination
2. Parallel combination

Series Combination of Capacitor—

When capacitors are arranged such that negative plate of one capacitor is connected to the positive plate of second one and the negative plate of second capacitor is connected to positive plate of third capacitor and so on, the arrangement is called series combination.

Let us have three capacitors of capacitance C₁, C₂ And C₃ which are connected in series with a voltage Source ‘V’ which set up a charge +Q and –Q Between the two plates of each capacitor.

 If voltage across each capacitor is V₁, V₂ and V₃ respectively then

Parallel Combination of Capacitor—

When capacitors are arranged such that positive plates of all the capacitors are connected to one common point and the negative plates of all the capacitors are connected to another common point, the arrangement is called parallel combination.

Let us have three capacitors of capacitance C₁, C₂ And C₃ which are connected in parallel with a Voltage Source ‘V’ which set up a charge Q₁, Q₂  and Q₃  between the two plates of the capacitors respectively Since, the capacitors are in parallel they have same potential difference between their plates then,
