The Capacitance of a Capacitor. Capacitance is the electrical property of a capacitor and is the measure of a capacitors ability to store an electrical charge onto its two plates with the unit of capacitance being the Farad (abbreviated to F) named after the British physicist Michael Faraday. Capacitance is defined as being that a capacitor has ...

where ΔPE is the potential energy, q is the charge, and ΔV is the change in voltage. To find the energy stored in a capacitor, you need to integrate this equation over the range of voltage from 0 to the final voltage (V) of the capacitor. This gives you the formula: E = ∫q × dV = ∫C × V × dV = 1/2 × C × V^2. where C is the capacitance.

The formula for this relationship is: E = 1/2 * Q^2 / C. Where: – E is the energy stored in the capacitor (in joules) – Q is the charge stored on the capacitor (in coulombs) – C is the capacitance of the capacitor (in farads) This formula is useful when the charge on the capacitor is known, rather than the voltage.

The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is ...
