Capacitors Basics
The capacitance of a capacitor is measured in a unit called the farad. Now, a farad is a pretty big unit, so capacitors used in everyday electronics are usually measured in microfarads (µF), nanofarads (nF), or even picofarads (pF). These smaller units represent a fraction or multiple of a farad, depending on the size of the capacitor.
