Power supply I use in my videos.

  • One farad (1F) capacitors will change their voltage by 1 volt each second that one amp of current flows. Those are very large values, so usually it is a fractional amount. For example, a 0.001F (1,000µF) capacitor with 0.001A (1mA) of current flowing, will also change voltage at a rate of 1V per second.
