How does tuning in a resonant circut work?

Tuning in a resonant circuit involves adjusting the circuit's components to achieve resonance, where the inductive and capacitive reactances balance each other out at a specific frequency. This is typically done by varying either the capacitance or inductance, allowing the circuit to selectively amplify signals at its resonant frequency while attenuating others. At resonance, the circuit exhibits maximum voltage and current, making it ideal for applications like radio frequency transmission and reception. The quality factor (Q) of the circuit also plays a crucial role, indicating how sharp or broad the resonance peak is.
