A capacitor is a device that stores electrostatic charge when an electric field is applied across it. The device also improves the power factor and reduces the transient current, which can otherwise damage expensive electrical equipment. While there are different types of capacitors, the basic structure consists of two conductors separated by a dielectric medium. The non-conducting dielectric increases the charge capacity. Various materials such as ceramic, glass, plastic film, vacuum, air, mica, or an oxide layer can act as a dielectric. A high-voltage capacitor can withstand up to 1 million volts while operating in a circuit. Improvement in the power factor can help reduce electricity loss.
