Question

Name the quantity which can be denoted by joule/coulomb.

Answer 1

Potential difference:

1. The potential difference between any two points may be defined as the amount of work done in moving a unit charge from one point to another.
2. Mathematically, $V=\frac{W}{q}=\frac{J}{C}$$\Rightarrow$Joule/coulomb., Where $W$= Work done, $q$= charge
3. This gives Joule per Coulomb as the SI unit of electric potential.
4. Electric potential is a scalar quantity.

Thus, Potential difference is the quantity that can be denoted by Joule per Coulomb.
