Which of the following instruments is used to check whether electricity is flowing through a substance or not?
- A. Ammeter
- B. Voltmeter
- C. Tester
- D. None of these
Step-by-step solution
A tester (such as a test lamp or continuity tester) is specifically designed to check whether electricity is flowing through a substance. An ammeter measures current but is not primarily used for simple flow checking, and a voltmeter measures voltage difference.
