WebA capacitor is made of two electrically conductive plates placed close to each other, but they do not touch each other. These conductive plates are normally made of materials such as aluminum, brass, or copper. The …
WebA variable capacitor is a type of capacitor that can be varied to change the capacitance. It is also known as an adjustable capacitor. The capacitance of a capacitor is the ability to store charge. The greater the capacitance, the greater amount of charge it can store. This can be varied by changing the distance between the capacitor plates.
