Capacitor Energy Calculator is a easy to use tool that finds the energy stored in a capacitor in no time. You just need to enter the values charge or capacitance, applied voltage in input field and click on the calculate button to obtain the Energy Stored in a Capacitor in a fraction of seconds.
What is Energy Stored in a Capacitor?
Capacitor is a commonly used electronic components in the circuits. Basically its function is to store electrical charge. In Parallel Plates Capacitors Charges of Equal but Opposite Values are present on adjacent plates. These charges generate electric field between them and includes a certain amount of circuit's energy.
Capacitor Energy Formula
If you want to estimate the Energy E stored in a Capacitor having Capacitance C and Applied Voltage then it is given by the equation E = 1/2 * C * V². You can rewrite this equation by applying the basic capacitance formula C = Q*V to get the other analogous form of capacitance equation i.e. E = 1/2 * Q² / C or E = 1/2 * Q * V
Energy in a Capacitor Example
If the capacitance of a capacitor is 60 F charged to a potential of 130 V, Calculate the energy stored in it.
Capacitance = 60F
Applied Voltage = 130V
We know the formula for Energy Stored E = 1/2 * C * V²
Substituting the input values we get the equation as E = 1/2*60*130²
E = 507 KJ
