microvolt

Millionth of volt

A microvolt is one millionth of a volt, used to measure extremely small electrical potentials.

The unit appears in contexts involving delicate signals—brain waves measured by EEG, nerve impulses, or sensitive electronic instruments: The signal registered only a few microvolts.
