The energy stored in a capacitor is the work done to move charge against the electric field between the plates. It’s an example of potential energy, which in this case, is stored in the electric field itself. Energy density is a measure of how much energy is stored in a given space.
The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
Charge Stored: Charge stored refers to the amount of electric charge that a capacitor can hold when connected to a voltage source. This stored charge is directly related to the capacitor's capacitance and the voltage applied across its plates, allowing it to temporarily hold electrical energy for later use.
So, the volume is (Ad). The total energy (U) stored in a capacitor is given by the formula: where (C) is the capacitance and (V) is the voltage across the plates. Energy density is the amount of energy stored per unit volume. For a capacitor, this refers to the energy stored in the electric field between its plates.
The final expression tells us that the energy stored in a capacitor is directly proportional to the square of the voltage across it and its capacitance. This means that if you double the voltage, the energy stored increases by a factor of four.
There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors. Dielectric capacitors encompass film capacitors, ceramic dielectric capacitors, and electrolytic capacitors, whereas supercapacitors can be further categorized into double-layer capacitors, pseudocapacitors, and hybrid capacitors.
