Question

When do we say that the potential difference across a conductor in a circuit is 1 volt ??

Answer 1

When the work done in carrying a unit positive charge from one point to the other is 1 joule.

Answer 2

Explanation:

The potential difference between two point is said to be 1 volt means if the work done in moving 1 coulomb charge from one point to other is 1 joule then it said to be 1 volt.

1 volt = 1 joule / 1 coulomb .
