Root Explanation

Ohmmeter → The word is formed from "ohm" (named after the German physicist Georg Simon Ohm, representing the unit of electrical resistance) and "-meter" (from Greek "metron", meaning measure). An ohmmeter is an instrument used to measure electrical resistance in ohms.

Memory Tip

Think of the term 'ohm' as a unit of resistance and '-meter' as a measuring device, so an ohmmeter is a tool that measures resistance in ohms.
