Root Explanation

Coulometer → It is formed from "coulomb" (named after Charles-Augustin de Coulomb, a French physicist, meaning a unit of electric charge) and "-meter" (from Greek "metron", meaning measure). The word refers to an instrument that measures electric charge in coulombs.

Memory Tip

Think of measuring electric charge, as 'coulomb' refers to the unit of charge and '-meter' indicates a measuring device.
