Capacitance Definition

Capacitance is defined as the charge-storing capacity of an electrical device. It is given by C = q/V where C is capacitance, q is charge and V is voltage. The unit of Capacitance is Farad denoted by “F”....

How are Capacitors Connected?

We can arrange for various capacitors to be connected with each other and the total capacitance of all the capacitors can be defined as the ratio of the total charge held by the capacitor and the total voltage applied in the circuit. This can be represented as,...

Series Combination of Capacitors

In the figure given below, three capacitors are connected in series with the battery of voltage V. Note that in the figure, opposite charges of equal magnitude flow and get accumulated on the plates of the capacitor. Conservation of charge principles requires that the charge that is accumulated on the plates of the capacitor must be equal in magnitude. The end result is a combination that resembles a single capacitor with an effective plate separation that is greater than that of individual capacitors, this equivalent capacitor is shown in the figure below. Large plate separation means smaller capacitance....

Parallel Combination of Capacitors

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. Thus capacitors have the same charges on them as they would have if connected individually to the voltage source....
