AI Customer ServiceWhen a capacitor is charged, the amount of charge stored depends on: its capacitance: i.e. the greater the capacitance, the more charge is stored at a given voltage. KEY POINT - The capacitance of a capacitor, C, is defined as:
This ability of the capacitor is called capacitance. The capacitance of a capacitor can be defined as the ratio of the amount of maximum charge (Q) that a capacitor can store to the applied voltage (V). So the amount of charge on a capacitor can be determined using the above-mentioned formula.
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
A charged capacitor can supply the energy needed to maintain the memory in a calculator or the current in a circuit when the supply voltage is too low. The amount of energy stored in a capacitor depends on: the voltage required to place this charge on the capacitor plates, i.e. the capacitance of the capacitor.
When a voltage V is applied to the capacitor, it stores a charge Q, as shown. We can see how its capacitance may depend on A and d by considering characteristics of the Coulomb force. We know that force between the charges increases with charge values and decreases with the distance between them.
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
