A milliamp is a unit used to measure electrical current and is equal to one one-thousandth of an ampere. The word milliamp is short for milliampere.. The ampere is the basic SI unit used to measure current, as established in 1948.
A mA, or milliamp, is 1/1000th of an amp, a measure of the flow of electrical current. It helps to think of electricity as water flowing down a pipe - the voltage is like the water pressure, the current (mA) is the amount of water flowing, and the resistance is the width of the pipe. Too much voltage can burn out your electronics, just like too much water pressure can burst your pipes.
