The negative of the potential gradient is equal to:
Correct answer: A. Electric field intensity
- A. Electric field intensity
- B. Electric flux
- C. Magnetic intensity
- D. Magnetic flux
Explanation
W = FdF = qEW = qEdW/q = V = EdV/d = EThe potential gradient is represented by -Δd/Δr. So, the potential gradient may be defined as the rate of change of electric potential with respect to position. Mathematically, E = -Δd/Δr Here, E is the electric field intensity. Hence, option A is the correct option.

About Electric Field Intensity
Electric field intensity is the force acting per unit positive test charge, with direction set by the force on that charge. Work includes fields of point charges, vector superposition, field lines and the relation between field and electric potential. Field intensity must be distinguished from electric force and potential.
