Quizplus · Accepted Answer

A varactor, also known as a voltage-controlled capacitor, is often used in electronic tuning circuits to change the resonant frequency of the circuit. This allows for precise tuning of the frequency for specific channels in television and FM receivers. Rectifiers, Schottky diodes, and tuning fuses are not typically used for electronic tuning.
