Variable Capacitor : Construction, Types and Their Applications
The applications of the variable capacitor include the following. Trimmer capacitors are used where a capacitance value is needed to be matched to a particular circuit in the manufacturing process. The main reason to use this capacitor is, the components used in the circuit have own tolerances. So the tolerance values can be changed by 20%
