Definitions:

Ammeter Function

The function of measuring the current flow in amperes in an electrical circuit, typically done by an ammeter.

Digital Multimeter (DMM)

A multiple mode electrical measurement instrument capable of measuring AC voltage, frequency, DC, ohms, amperage, and other values. The term DMM tends to be used in truck technology; the same instrument is more commonly referred to as a digital volt ohmmeter (DVOM) in the auto area.

Circuit

A closed path through which electrical current flows or can flow.

Cathode

The electrode in a battery or electrochemical cell towards which positive ions move, typically where reduction reactions take place.
