Conversation

Have you ever used an electrometer for your experiments?

No, I haven't, but I've heard they are really useful for measuring voltage.

Yeah, they can also detect potential differences in various setups.

That sounds interesting! I should look into getting one for my next project.

Root Explanation

Electrometer → It is formed from "electro-" (from Greek "ēlektron", meaning amber or electricity) and "meter" (from Greek "metron", meaning measure). The word "electrometer" refers to an instrument that measures electric charge or electrical potential.

Memory Tip

Think of 'electricity' ('electro-') being 'measured' ('meter') — that's what an electrometer does.
