This is a <a href="http://en.wikipedia.org/wiki/Tesla_coil">tesla</a>
<a href="http://www.richieburnett.co.uk/operation.html">coil</a>
circuit. A transformer steps the input voltage up 100x to create a high
voltage. After a few seconds, the voltage is high enough to fire the
spark gap. The capacitor and the primary coil of the second transformer
then form a resonant circuit. The secondary transformer coil is attached
to a toroid, represented here by a capacitor connected to ground. It
also forms a resonant circuit with the same resonant frequency, about 200kHz
The energy is <A href="http://www.richieburnett.co.uk/operation.html">gradually
transferred from the first circuit to the second</a>, and then the
spark gap stops conducting, leaving all the energy in the toroid circuit.
<p>
Once the spark gap stops conducting, it takes a while for the voltage to
build up enough for it to fire again. The simulation speed is slowed down
quite a bit so that the 200kHz oscillations can be seen.
You might want to reload the circuit
instead of waiting.
