The electric potential at a point in an electric field is the amount of work done to move:
Correct answer: B. A unit positive charge from infinity to that point
- A. Any amount of charge from infinity to that point
- B. A unit positive charge from infinity to that point
- C. Any amount of charge from any position to that point
- D. A unit negative charge from infinity to that point
Explanation
This is the definition of electric potential.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
