Question

The device used for measuring potential differences is known as

• A. potentiometer
• B. ammeter
• C. voltmeter
• D. galvanometer

Answer 1

The correct option is C

voltmeter

Explanation for the correct option(s):

C. Voltmeter
A voltmeter is an electrical device used to measure the potential difference between the two points.

Explanation for the incorrect options:

A. Potentiometer
The energy utilized between two places in a circuit is measured by the potential difference between two points on each side of a component.
A potentiometer is an electrical device used to adjust the potential across the terminals.

B. Ammeter
An ammeter is an electrical device used to measure the flow of the current through it.

D. Galvanometer
A galvanometer is an electrical device used to detect the flow of a small current through it.

So, the device used for measuring potential differences is known as a voltmeter. Thus, option C is the correct answer.
