milliamperek

Milliamperek is a unit of electric current. It is a submultiple of the ampere, the SI base unit for electric current. The prefix "milli" indicates one-thousandth. Therefore, one milliampere (mA) is equal to one-thousandth of an ampere (A).

In practical terms, the milliampere is commonly used to measure small electrical currents found in many electronic devices and circuits. For example, the current drawn by a light-emitting diode (LED) is often measured in milliamperes. Similarly, the output current of small power supplies, batteries, and sensors is frequently expressed in milliamperes.

The relationship between milliamperes and amperes is straightforward: 1 A = 1000 mA, and conversely, 1 mA = 0.001 A. This unit is essential for understanding and specifying the electrical performance of a wide range of electronic components and systems where the current is too small to be conveniently expressed in amperes. When working with electrical schematics or device specifications, observing values in milliamperes provides a clear indication of the expected current flow.
