Experimentally, it has been found that, the charge Q stored in a capacitor is directly proportional to the voltage across it, i.e. Where, C is a constant and is called as capacitance of the capacitor. Thus, the capacitance (C) of a capacitor can also be defined as the ratio of the charge on the either plate to the voltage across it.
Equation 1 is the required formula for calculating the capacitance of the capacitor and we can say that the capacitance of any capacitor is the ratio of the charge stored by the conductor to the voltage across the conductor. Another formula for calculating the capacitance of a capacitor is, C = εA / d
The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device: C = Q V
It is denoted with the symbol C and is defined as the ratio of the electric charge stored inside a capacitor by the voltage applied. Thus, any material that has a tendency to store electric charge is called a capacitor and the ability of the material to hold electric charge is called the capacitance of the material.
