microampere
Minute electrical flow
A microampere is one millionth of an ampere—a unit for measuring extremely small electrical currents.
The abbreviation is μA.
Microamperes appear in specifications for low-power electronics, medical devices, and sensitive instrumentation where currents are too tiny to measure in milliamps: The sensor draws only 50 microamperes in sleep mode.
