This circuit image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file "Tuned circuit animation 3.svg" - then the template Vector version available (or Vva) does not need the new image name parameter.

DescriptionTuned circuit animation 3.gif
English: Animated diagram showing the operation of a tuned circuit (LC circuit). This is an improvement over previous versions of this animation which uses variable frame display times to show a more realistic movement of the charge.
A tuned circuit is a very simple electronic circuit widely used in audio, radio and television equipment. It consists of an inductorL (coil of wire, left) and a capacitorC (right) connected together. Tuned circuits can store electrical energy oscillating at its resonant frequency. The capacitor stores energy in its electric fieldE and the inductor stores energy in its magnetic fieldB (green). When the capacitor is charged with electricity and connected to the coil, the charge flows back and forth between the capacitor's plates as a current i (red) through the coil as shown. This jerky animation shows "snapshots" of the circuit at progressive points in the oscillation. The oscillations are slowed down; in an actual tuned circuit the charge oscillates back and forth hundreds of thousands to billions of times per second.
