Explanation:

Work done per unit coulomb:
- Work done per unit coulomb is known as electric potential, which is measured in volts (V).
- It represents the amount of work done in moving a positive test charge from one point to another in an electric field.

Electric potential:
- Electric potential is a scalar quantity that represents the amount of work needed to move a unit positive charge from a reference point to a specific point in an electric field.
- It is defined as the electric potential energy per unit charge.

Relationship between work done per unit coulomb and electric potential:
- Work done per unit coulomb and electric potential are closely related concepts but are not the same.
- While work done per unit coulomb is the work done in moving a charge, electric potential is the potential energy per unit charge at a point in an electric field.
- Electric potential is equal to the work done per unit charge only in a uniform electric field.

Conclusion:
- Work done per unit coulomb is not equal to electric potential, but they are related concepts in the field of electricity.
- Understanding the difference between the two is crucial for grasping the fundamental principles of electrostatics and electric fields.
