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
The capacitance formula provides a straightforward way to quantify how much charge a capacitor can store at a given voltage. It is expressed as: C is capacitance, measured in farads (F). Q is the charge stored, measured in coulombs (C). V is the voltage across the capacitor, measured in volts (V).
This formula is pivotal in designing and analyzing circuits that include capacitors, such as filtering circuits, timing circuits, and energy storage systems. Capacitor voltage, V c (V) in volts is calculated by dividing the value of total charge stored, Q (C) in coulombs by capacitance, C (F) in farads. Capacitor voltage, V c (V) = Q (C) / C (F)
Q (C) = total charge stored in coulombs, C. C (F) = capacitance in farads, F. Given: Q (C) = 0.002C, C (F) = 0.0001F. Capacitor voltage, V c (V) = Q (C) / C (F)
Definition: Capacitance is the ability of a capacitor to store electric charge per unit of voltage, measured in farads (F). Role in circuits: Capacitance defines the capacity of a capacitor to stabilize, filter, or store energy in electronic systems. How Capacitance is Measured
In the case of series connection of capacitors, the reciprocal of the equivalent capacitance is equal to the sum of the reciprocals of the capacitances of the capacitors. In the case of parallel connection of capacitors, the equivalent capacity is equal to the sum of the capacities of the capacitors.
