Study of Resonance phenomena and it�s applications
Dr. G. Patrick
Resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies. Frequencies at which the response amplitude is a relative maximum are known as the system�s resonant frequencies or resonance frequencies. At resonant frequencies, small periodic driving forces have the ability to produce large amplitude oscillations, due to the storage of vibrational energy.

- Most common application of resonance is tuning fork i.e., as an oscillator circuit.
- A series resonant circuit is used as Voltage Amplifier.
- A parallel resonant circuit is used as Current Amplifier.
- A resonant circuit is used as Filter.
- A realistic parallel resonant circuit is used as a current rejector.
- A parallel resonant circuit is used as Load impedence in output circuits of RF amplifiers.
- A parallel resonant circuit can be used in induction heating.
