A tank circuit is an electrical circuit consisting of a capacitor connected to an inductor, by conducting wires that use magnetic resonance to store electrical energy oscillating at a certain resonating frequency. It is used to produce electric oscillations of any desired frequency.
Because opposite charges cannot flow through the surface but it attracts. The charges will supply to the inductor coil through the connecting wires to charge the inductor in electromagnetically. The circuit diagram of the tank circuit is shown below. The circuit can be built using electrical and electronic components like an inductor and capacitor.
The tuned circuit's action, known mathematically as a harmonic oscillator, is similar to a pendulum swinging back and forth, or water sloshing back and forth in a tank; for this reason the circuit is also called a tank circuit.…… LC circuit - Wikipedia 百科里讲，LC谐振回路里的电流就像单摆，前后摆来摆去；又像水槽里的水，来回晃动，因此被称作槽路。 其电流振荡如下图所示： David Halliday.
The circuit can act as an electrical resonator, an electrical analog of a tuning fork, storing energy oscillating at the circuit's resonant frequency. LC Tank oscillator circuits are used for producing signals at a certain frequency or choosing a signal at a particular frequency from a more complex signal.
The natural frequency or the frequency of the oscillations in the circuit is determined by the capacitance and inductance values. The tank circuit's circuit diagram is displayed below. Electrical and electronic parts like an inductor and capacitor can be used to build the circuit.
A tank circuit acts as a resonant circuit because of the movement of charges between the capacitor and the inductor. The energy oscillating back and forth between the capacitor and the inductor dies out because of the internal resistance of the circuit if it is not driven by an external source.

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.
