Definition - What does Capacitor mean?
A capacitor is an electronic device that stores electrostatic energy. It is composed of two conducting metallic plates separated by an insulating material. Capacitors are very common in electronic devices including radios, TVs, cell phones and computers.
Corrosionpedia explains Capacitor
Capacitors are measured according to their ability to store an electrical charge. This rate is known as capacitance and is measured in the unit of Farads. Capacitance is directly proportional to the surface area of the composite plates in the capacitor and inversely proportional to the distance between the plates.
Capacitance is an indication of the rate of corrosion resistance of a metal surface. The capacitance is directly proportional to the susceptibility to corrosion.
