Answer:
Tuning of radio set is an example of Electric resonance.
Explanation:
- When the impedances or admittances of circuit elements cancel one another, electrical resonance occurs in an electric circuit at a specific resonant frequency.
- This occurs in some circuits when the transfer function is very close to one and the impedance between the circuit's input and output is almost zero.
- Resonant circuits produce higher voltages or currents than are supplied into them and exhibit ringing.
- They are frequently employed for both transmission and reception in wireless (radio) transmission.
- When inductors and capacitors are used in a circuit, resonance happens because the inductor's magnetic field collapses, creating an electric current in its windings that charges the capacitor, and the capacitor discharges, creating an electric current that strengthens the inductor's magnetic field.
