The circuit he’s building here is a solar charger for the super capacitor. Being a fairly small device there’s not a lot of current, voltage, or energy, but these are different enough from ...

The best part by far, though, was the demonstration of drawing an arc from a high voltage power supply with and without the capacitor in the circuit. As you might expect, playing with a few ...

Capacitors are common in all manner of electrical circuits ... separated by an insulator. When a voltage is applied, one surface takes on a positive charge while the other takes on a negative ...
