• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
Capacitance and capacity are two related concepts that are often used interchangeably, but they have distinct meanings in the field of electronics. Capacitance refers to the ability of a component, such as a capacitor, to store electrical energy in the form of an electric field. It is measured in farads and is a property of the component itself.
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
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
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.
If by "capacity" you mean the amount of net charge on the plates, then obviously that's not the same as the capacitance of the capacitor which is the charge divided by the voltage. The capacitance of a capacitor is greater if the work required per unit charge to separate the charge on the plates (i.e., the voltage) is less. Hope this helps.
