Capacitors
A capacitor is almost like a small battery, it can be charged
using a power supply. Mostly used to stabilise or to filter out
unwanted voltages. The unit is Farad: practical values are
in µF, nF or pF. The supplied capacitor is an Electrolytic
capacitor of 10µF and has a polarity, the long lead = +
