What is the relationship between electric field and electric potential?

Step 1: Understand that electric potential (V) is a measure of the potential energy per unit charge at a point in an electric field.
Step 2: Recognize that the electric field (E) is a vector that represents the force experienced by a positive charge placed in the field.
Step 3: Learn that the electric field is related to how the electric potential changes in space.
Step 4: The relationship is expressed mathematically as E = -dV/dr, where dV is the change in electric potential and dr is the change in distance.
Step 5: The negative sign indicates that the electric field points in the direction of decreasing electric potential.
