Question

Resonant circuits are used in the tuning of

Answer 1

Resonant circuit:

1. An electric circuit that has a very low impedance at a certain frequency.
2. Resonant circuits are often built using an inductor, connected in parallel to a capacitor.
3. In an alternating current, if the phase of the applied potential difference and the current flowing in the circuits are the same, then the circuit is called a resonant circuit.
4. The frequency at which resonance occurs is called the resonant frequency.

There are two types of the resonant circuits:

1. Series resonant circuit
2. Parallel resonant circuit

The diagram to represent the resonant circuit:

Hence, resonant circuits are used in radio and television tuners to pick out broadcast signals of specific frequencies.
