Question

the potential difference between two points in an electric circuit is 1v. What does it mean?Name a Device that helps to measure the potential difference across a conductor​

Answer 1

Answer:

potential difference between two points in an electric circuit carrying current is defined as the work done to move a unit positive charge from one point to another.

the SI unit of electric potential difference is volt where 1 volt = 1joule / 1 coulomb

potential difference across a conductor can be measured by voltmeter

Answer 2

Answer:

voltmeter

Explanation:

the above sentence means the work done to move a unit positive charge from one point to another is 1 volt . the device used to measure potential difference is voltmeter
