The energy of a capacitor is calculated using the equation W = Q · V, where W is the work, Q is the charge, and V is the voltage. However, in a capacitor, we must consider the nonideality of the charging process. The charge accumulated in the capacitor starts at 0 and ends at Q after a certain time.
The following formulas and equations can be used to calculate the capacitance and related quantities of different shapes of capacitors as follow. The capacitance is the amount of charge stored in a capacitor per volt of potential between its plates. Capacitance can be calculated when charge Q & voltage V of the capacitor are known: C = Q/V
When a voltage difference (potential difference) is applied across a component or system, it refers to the capacity of that component or system to store an electric charge. The ratio of the magnitude of the charge (Q) held on one of the plates to the potential difference (V) between the plates is known as a capacitor’s capacitance (C):
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
C = Q/V If capacitance C and voltage V is known then the charge Q can be calculated by: Q = C V And you can calculate the voltage of the capacitor if the other two quantities (Q & C) are known: V = Q/C Where Reactance is the opposition of capacitor to Alternating current AC which depends on its frequency and is measured in Ohm like resistance.
The amount of energy that can be stored in a capacitor’s dielectric material between its plates per unit volume is referred to as the capacitor’s energy density. The amount of energy stored in the electric field between the plates in relation to the volume of the capacitor is shown by this measurement.
