Question

The AC voltage across a resistance can be measured using _______________

Answer 1

Explanation

1. The hot wire voltmeter is based on the variation in the resistance of the wire with temperature.
2. Hot-wired devices can measure any quantity for both AC and DC supply.
3. A voltmeter is used to measure voltage.
4. So a hot-wired voltmeter can measure the voltage of Ac and DC supply.
5. So the AC voltage across a resistance can be measured by a hot-wired voltmeter.

Hence, the answer is a hot wire voltmeter.
