An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together.

Where are tuned circuit used?

Tuned Circuit Properties

Much smaller ones are used in receivers. A tuned circuit has a very high impedance at its resonant frequency (ideally = infinity). At other frequencies, its impedance is lower. Tuned circuits are used to select or tune in radio stations on a particular frequency and reject all the others.

What is use of tuned circuit?

A circuit in tuned amplifier present at the load which consists of the inductor and the capacitor connected in parallel to each other is known as a tuned circuit. The purpose of the tuning circuit is to set the desired range of frequencies known as the resonant frequency.
