Electric Charge and Field: Fundamental principles guiding capacitor operation. Impedance and Reactance: Capacitor's resistance to changes in current.
The charge that a capacitor can store is proportional to the voltage across its plates. When a voltage is applied across the capacitor, the current flows from the voltage source to the capacitor plates. As the capacitor charges up, the current gradually decreases until it reaches zero.
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone.
The amount of electrical charge that can be stored in the capacitor is determined by the capacitor's capacitance. The capacitance of a capacitor depends on the plate area, the distance between the plates, and the type of dielectric material used.
Also, because capacitors store the energy of the electrons in the form of an electrical charge on the plates the larger the plates and/or smaller their separation the greater will be the charge that the capacitor holds for any given voltage across its plates. In other words, larger plates, smaller distance, more capacitance.
A capacitor can retain its electric field -- hold its charge -- because the positive and negative charges on each of the plates attract each other but never reach each other. At some point the capacitor plates will be so full of charges that they just can't accept any more.
