When a voltage is applied, an electric field develops across the dielectric, causing the capacitor to store energy in the form of an electrostatic charge. Capacitors differ from batteries in that they store energy in an electric field rather than through chemical reactions, enabling them to charge and discharge at much faster rates.
A: The energy stored in a capacitor can change when a dielectric material is introduced between its plates, as this can increase the capacitance and allow the capacitor to store more energy for the same applied voltage. Q: What determines how much energy a capacitor can store?
Capacitance: The higher the capacitance, the more energy a capacitor can store. Capacitance depends on the surface area of the conductive plates, the distance between the plates, and the properties of the dielectric material. Voltage: The energy stored in a capacitor increases with the square of the voltage applied.
A: Capacitors store and release reactive power in the form of an electric field, but they do not consume true power, which is the power dissipated in resistive components of a circuit. Q: Can a capacitor burn a motor?
A: The principle behind capacitors is the storage of energy in an electric field created by the separation of charges on two conductive plates. When a voltage is applied across the plates, positive and negative charges accumulate on the plates, creating an electric field between them and storing energy.
In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals.

How Capacitors Work
A capacitor is an electrical component that draws energy from a battery and stores the energy. Inside, the terminals connect to two metal plates separated by a non-conducting substance. When activated, a capacitor quickly releases electricity in a tiny fraction of a second.

Electrolytic capacitor
Like other conventional capacitors, electrolytic capacitors store the electric energy statically by charge separation in an electric field in the dielectric oxide layer between two electrodes.The non-solid or solid electrolyte in principle is the cathode, which thus forms the second electrode of the capacitor.

Capacitors
The problem is capacitors have a much lower energy density than batteries; they just can''t pack as much energy as an equally sized chemical battery (but that gap is narrowing!). The upside of capacitors is they usually lead longer lives than batteries, which makes them a better choice environmentally.
