"""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.
|
||
|
|
The circuit can act as an electrical resonator, an electrical analogue of a
|
||
|
|
tuning fork, storing energy oscillating at the circuit's resonant frequency.
