The Circuit That Sloshes

You'll learnwhat a charged capacitor does across a coil: it does not just empty - the charge sloshes back and forth forever, like a mass on a spring.

Charge a capacitor, connect it across a big coil, and let go. It does not quietly empty itself: it empties, overshoots, charges up the other way round, and comes back, over and over, forever. Twelve short steps; press Next for each one.

Before you start

What you're looking at

A charged capacitor and a coil in one loop, with no battery and no resistor. The violet bar is the charge; the teal arrow is the current.

The question

What happens when the capacitor is allowed to empty through the coil?
