Reliable Testing of Capacitors

A capacitor is an electronic device that consists of two conducting plates bearing opposite electronic charges, having dielectric (insulator) medium as their separator. Different capacitors may make use of different dielectric. Mostly include air, paper, and plastic, polyester and polystyrene. A potential difference across the conducting plates causes the formation of a static electric field in the dielectric. Capacitor stores energy between the two conductors where the electric field is present. Charging is the process allows the capacitor to store energy. The capacitor has a wide range of application in electronic circuits with the purpose of restricting direct current (DC) and allowing alternating current (AC) to pass through. The device is basically built for storing energy and for releasing all the energy at once. The capacity of this device to hold an electrical charge is termed as 'capacitance' and it is measured by Farads. For the measurement of electric charge between the two conducting plates is measured in the reliable methodology is described below.
