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 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
This constant of proportionality is known as the capacitance of the capacitor. Capacitance is the ratio of the change in the electric charge of a system to the corresponding change in its electric potential. The capacitance of any capacitor can be either fixed or variable, depending on its usage.
So, the dimensional formula for the capacitance is [M-1L-2T4I2]. One can get three graphs for a capacitor – Capacitance vs Charge graph (C-Q graph), Capacitance vs Voltage graph (C-V graph) and Voltage vs charge graph (V-C graph). Here, I am going to draw each graph one by one and will discuss the nature of all graphs.
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.
Capacitor and Capacitance are related to each other as capacitance is nothing but the ability to store the charge of the capacitor. Capacitors are essential components in electronic circuits that store electrical energy in the form of an electric charge.
