Resonant circuit

Applications

• The most common application of tank circuits is tuning radio transmitters and receivers. For example, when tuning a radio to a particular station, the LC circuits are set at resonance for that particular carrier frequency.
• A series resonant circuit provides voltage magnification.
• A parallel resonant circuit provides current magnification.
• A parallel resonant circuit can be used as load impedance in output circuits of RF amplifiers. Due to high impedance, the gain of amplifier is maximum at resonant frequency.
• Both parallel and series resonant circuits are used in induction heating.
