Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for impedance matching in antenna tuners.
In order to adjust capacitance, a variable capacitor modifies the surface area of its overlapping plates. A variable capacitor, sometimes referred to as a tuning capacitor, is a kind of capacitor in which the capacitance can be mechanically or electrically altered on a regular basis.
The capacitors with the capacitance value are fixed are known as ‘Fixed Capacitors’. Similarly, the capacitors that are with varying amounts of capacitance are known as Variable Capacitors. This type of capacitor has the capability of changing the values of its capacitance either “Electrically” or “Mechanically”.
The difference between the value of a variable capacitor as it is and the value that it should have based on a given table is its accuracy. One can limit the accuracy of a variable capacitor by understanding the physics of capacitors.
