Electric potential energy per unit charge at a point in space is given a special name. What is that quantity called, and in what unit is it measured?

1. Electric potential energy per unit charge is defined as the electric potential, V. 2. Its SI unit is the volt, since a volt is a joule per coulomb. 3. Electric field, electric charge, and magnetic field are each a different physical quantity from electric potential, so naming any of them here is wrong even though every option is labeled in volts. _Source: OpenStax Physics (CC BY 4.0), Ch 18 "Static Electricity", section Electric Potential_
