The variable capacitor functions as the tuner in a radio, allowing the receiver to select the desired frequency.
The component of a radio that performs the function of the tuner is the variable capacitor. In a radio receiver, the tuner circuit resonates at a specific frequency, allowing it to respond strongly to the desired frequency while rejecting others. Variable capacitors are used to adjust the resonant frequency for tuning into different stations.
