About Current Units
Electric current is measured in amperes (A) and describes the rate at which charge flows through a conductor.
Current in electronics ranges from the nanoamps drawn by a sleeping microcontroller to the tens of amps in a motor driver. Battery-life estimates hinge on getting these prefixes right — confusing microamps with milliamps overstates sleep current by 1000x.
Example conversions
- 80 mA = 0.08 A — an active Wi-Fi radio burst.
- 10 µA = 0.01 mA — a deep-sleep current draw.
