WebThe capacitor explained is constituted by three pairs of metal plates and dielectrics that can be easily recognized from its outer structure. The legs, the uppermost metal plate and the screw which is used to change the capacitance, are easily observable from the first sight as the cap of the capacitor is transparent. 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.
