Question
Which instrument would you use to measure electric potential?
Answer Options
- A) An ammeter
- B) A voltmeter
- C) A wavemeter
- D) An ohmmeter
Correct Answer: B
Explanation
Electric potential is the electrical pressure or force that causes current to flow, and the technical term for this is voltage (T5A05). The instrument used to measure voltage is a voltmeter.
A voltmeter is typically connected in parallel across the two points in the circuit where you want to measure the potential difference (T7D02). Modern multi-meters include a voltmeter function, along with an ammeter and ohmmeter.
