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
• 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.
Quality factor is the dimensionless ratio of reactance to resistance in a capacitor. Capacitors are passive devices used in electronic circuits to store energy in the form of an electric field.
Since capacitance is the charge per unit voltage, one farad is one coulomb per one volt, or 1F = 1C 1V. By definition, a 1.0-F capacitor is able to store 1.0 C of charge (a very large amount of charge) when the potential difference between its plates is only 1.0 V. One farad is therefore a very large capacitance.
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
The Average power of the capacitor is given by: Pav = CV2 / 2t where t is the time in seconds.
