Amps

A multimeter - also known as a VOM (Volt-Ohm meter or Volt-Ohm-milliammeter) - is a gizmo for measuring voltage, amperage, and other electronic measurements. Basic multimeters measure volts, amps and resistance, and fancier units have other capabilities. Generally speaking multimeters are used for basic electrical measurements, or finding faults in electrical circuits.

Electricity has three measurements, the volt, the amp, and the watt.
