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 ...

Those power supplies and analog circuits often have a number of old aluminium electrolytic capacitors of unknown ... increased ripple current in power supply applications.

A power tip that discusses how to address highly integrated USB PD charger design constraints with a self-biasing circuit.
