Question

What is the relationship between 1 volt and 1 joule?

Answer 1

We know that potential difference is the work done in bringing a unit positive charge from one point of the conductor to another.

Thus, 1V = 1J/1C
Where V = Volt, J = Joule, C = Coulomb

Answer 2

One volt is the potential difference between two points in a current carrying conductor when 1 joule of work is done to move a charge of 1 coulomb from one point to the other 1 volt is equal to 1 joule upon one coulomb
