Q: The voltage is measured using a voltmeter, which measures which difference across two points?


Read this paragraph and choose the correct option from the provided answers:

A uniform electric field makes it easier to measure the difference in electric potential energy. This energy, also called the electric potential difference is commonly referred to as the voltage , based on the unit, volt (V). To measure the voltage across some distance, it is necessary to pick a position to be the relative zero, because voltage is the change in potential difference. Any point in a system can be given the value of zero volts, but it is typically the point of a point charge or one plate in a uniform electric field as shown above. The voltage is measured using a voltmeter, which measures the electric potential difference across two points.

 Choices:

- Distance

- actual difference

- average difference

- potential difference


A:
potential difference
