What instrument is used to measure electrical current?
- AAmmeter
- BWavemeter
- CWattmeter
- DVoltmeter
Correct answer: A — Ammeter. From the official ISED question bank, verified word for word.
Why
An Ammeter measures electrical current, which is the flow of electric charge through a wire, much like a water meter tracks how much water moves through a pipe. The full explanation — and one for every question — is in Pro.
