Question

A voltmeter has a high ___________ .

Answer 1

1. A voltmeter is a device used to determine the potential difference in a circuit.
2. It is connected in parallel to the circuit.
3. This is done because the resistance of the voltmeter is very high.
4. The resistance of an ideal voltmeter is infinite.
5. The voltmeter in parallel combination will allow negligible current to flow through it.
6. Thus, maximum current flows through the circuit giving accurate readings.
7. The potential difference between the ends of the voltmeter is given as its reading.

Hence, a voltmeter has a high resistance.
