The negative of potential gradient is equal to:
Correct answer: A. Electrical intensity
- A. Electrical intensity
- B. Electric flux
- C. Magnetic intensity
- D. Magnetic flux
Explanation
The electric field at any point is negative of the potential gradient; as we proceed from the positive charge and toward the negative one, the electrostatic potential changes. (A negative sign indicates that the potential is decreasing).

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.
