Key Stage 3
Meaning
A voltmeter is a measuring device used to measure the potential difference between two points in a circuit.
About Voltmeters
- Voltmeters are added in parallel to components in a circuit to find the potential difference between two points.
- An ideal voltmeter has infinite resistance because otherwise adding an voltmeter to a circuit would change the Potential Difference between two points.
- Voltmeters can be analogue with a needle pointing to numbers on a dial or it can be digital with a number display.
