Answer 1

Answer:

The correct statement that defined a volt is b) A volt is a joule per coulomb

Volt is a joule per coulomb because joule is a unit of work done while coulomb is a unit for the charge. The ratio of work done to the charge is the definition of potential and volt is the unit of potential difference. Therefore, it can be said that one joule per coulomb is equal to the unit of the potential difference which is also equal to one volt.

(1 Joule)/(1Coulomb) = 1Volt
