LC circuit

{tag=Spring-mass system}

Both are <harmonic oscillators>.

In the <LC circuit>:
* the current current may be seen as the velocity and containing the <kinetic energy>
* the charge stored in the capacitor as the <potential energy>

You can kickstart motion in either of those systems in two ways:
* charge the capacitor, i.e. pull the string, and then let it go, i.e. close the circuit. This is the simpler one to realise. Shown concretely at: <video LC circuit dampened oscillations on an oscilloscope by Queuerious Guy (2014)>
* give speed to the mass, i.e. make a current pass through the inductor


An LC circuit is analogous to a spring-mass system
