microamp
Millionth of ampere
A microamp is one millionth of an ampere, used to measure extremely small electrical currents.
The unit appears in electronics, medical devices, and scientific instruments where currents are too tiny for standard measurement: The sensor draws only a few microamps.
Also written as microampere or abbreviated μA.
