Answer:
A parallel LC resonant circuit is used as a Filter.
Explanation:
In LC parallel resonant circuit, the impedance is near infinity or very high. Since the impedance(resistance) is maximum, the current is negligible or zeroes it circulates back and forth between components without involving the source. A parallel resonance circuit only functions on the resonant frequency, this type of circuit is also known as a Rejecter Circuit.
Being a parallel resonance means the impedance is high and inrush surges current relatively low compared to a simple capacitor. These are used in radio and television tuners to pick out broadcast signals of specific frequencies.
The parallel resonance circuits are used as a
- Tuning purpose.
- Induction heating systems.
- Current Amplifiers.
- Filter circuits.
