Plural of farad, the unit of electrical capacitance used to measure how much electric charge something can store.
Named after Michael Faraday, the 19th-century English physicist who discovered electromagnetic induction. The unit was officially adopted in the late 1800s to honor his contributions to electrical science.
A farad is enormous—one farad of capacitance is so huge that you'd never find it in everyday electronics! Most real circuits use microfarads or nanofarads instead, which shows how powerful Faraday's discoveries about electricity really were.
