Electric potential is measured in units of ____________________. A) watts.B) joules per coulomb, or volts.C) joules.D) ohms.E) amperes.

To find out the units for measuring electric potential, we can start by understanding what electric potential represents. Electric potential is the amount of potential energy per unit charge at a point within an electric field.

The unit for potential energy is measured in joules (J), and the unit for charge is measured in coulombs (C). So, electric potential, which is the potential energy per unit charge, is measured in joules per coulomb (J/C).

Therefore, the correct answer is B) joules per coulomb or volts.
