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
In summary, the capacitance formula is an essential tool in understanding and designing capacitors, allowing engineers and scientists to optimize electronic circuits for a variety of applications. Let’s consider a parallel plate capacitor with the following parameters:
It is defined as the ratio of the charge stored (Q) to the potential difference (V) across the capacitor. Mathematically, this is expressed as: Here, ‘C’ represents the capacitance, measured in farads (F), ‘Q’ denotes the charge in coulombs (C), and ‘V’ stands for the voltage in volts (V).
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
Parallel plate capacitor - circular plates. The formula for the capacitance of a parallel plate capacitor is: ε r = relative permitivity of the dielectric (less commonly known as K, the dielectric constant) The diagrams show parallel plate capacitors with different shaped plates, one rectangular and one circular.
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.
