Customer ServiceA Capacitor is a two terminal electronic device that has the ability to store electrical energy in the form of electric charge in an electric field. It is a physical object. It consists of two conductors generally plates and an insulator (air, mica, paper, etc.) separated by a distance.
One relatively easy factor to vary in capacitor construction is that of plate area, or more properly, the amount of plate overlap. The following photograph shows an example of a variable capacitor using a set of interleaved metal plates and an air gap as the dielectric material:
Capacitors are potentially dangerous because they store a significant amount of energy. Short-circuiting or mishandling a charged capacitor results in a rapid discharge, causing sparks, burns, or even an electric shock. In extreme cases, large capacitors deliver a potentially lethal shock.
Capacitor is one of the basic components of the electric circuit, which can store electric charge in the form of electric potential energy. It consists of two conducting surfaces such as a plate or sphere, and some dielectric substance (air, glass, plastic, etc.) between them.
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
The value of this current is affected by the applied voltage, the supply frequency, and the capacity of the capacitor. Since a capacitor reacts when connected to ac, as shown by these three factors, it is said to have the property of reactance — called capacitive reactance.
