Milliampere Unit | All you need to know
A milliampere (mA) is a unit of electric current equal to one thousandth of an ampere (10^-3 amperes). Milliamperes are standard in electronic circuits, consumer electronics, and biomedical devices. Battery chargers, LED circuits, and medical equipment like TENS units operate at milliampere ranges. The milliampere is practical and widely understood in electronics, appearing on device specifications, user manuals, and equipment labels. Battery capacity is often rated in milliampere-hours (mAh), making the unit familiar to anyone using rechargeable devices.
