Farad

/ˈfærəd/ noun

Definition

The unit of measurement for electrical capacitance, named after physicist Michael Faraday; it measures how much electric charge something can store.

Etymology

Named in honor of Michael Faraday, the 19th-century English scientist who discovered electromagnetic induction. The unit was officially adopted to commemorate his groundbreaking work in electricity and magnetism.

Kelly Says

Farad's huge unit (1 farad is enormous—most real capacitors are measured in microfarads) tells you something remarkable about Faraday's legacy: he was so important that scientists named a unit after him even though it's almost never used in its full form, like naming a length unit after someone but only using millionths of it.
