The correct relation between electric intensity E and electric potential V is

• A: E = − (dV / dr)
• B: E = − (dV / dr)
• C: V = − (dE / dr)
• D: V = − (dE / dr)

The relationship between electric intensity (E) and electric potential (V) is fundamental in understanding electric fields. The correct equation that describes this relationship is:

Correct Relation

E = - (dV / dr)

Explanation of Terms

• E: Electric intensity or electric field strength.
• V: Electric potential.
• dV: Change in electric potential.
• dr: Change in position or distance.

This equation indicates that the electric field is the negative gradient of the electric potential. In simpler terms, it shows how the electric field points in the direction of decreasing potential.
