What are the rules for equipotential lines and feature of the equipotential map indicates where the electric field is strongest?
Rules for equipotential lines:
Feature of the equipotential map indicates where the electric field is strongest:
The spacing of the equipotential lines is the most important feature that indicates where the electric field is strongest. In regions of stronger electric field, the equipotential lines are spaced closer together. This is because the electric field is proportional to the rate of change of the electric potential. Therefore, where the electric potential is changing rapidly, the electric field is strong.
For example, the electric field is strongest between two oppositely charged plates. This is because the electric potential is changing rapidly between the plates. The equipotential lines on an equipotential map are spaced closer together between the plates than they are elsewhere. This indicates that the electric field is stronger between the plates than it is anywhere else.

equipotential lines
In addition to the spacing of the equipotential lines, the direction of the equipotential lines can also be used to indicate the direction of the electric field. The electric field is always perpendicular to the equipotential lines, and it points from higher potential to lower potential.
Therefore, by looking at the spacing and direction of the equipotential lines on an equipotential map, you can determine the strength and direction of the electric field at any point in space.
Yes, densities parts of the equipotential maps illustrate where the electrical field is strongest lines are angled. This means that the greater the angles, the greater the spreading. Therefore, the electric field is indeed strongest near the electrodes. The equipotential lines can be drawn by making them perpendicular to the electric field lines, if those are known. Note that the potential is greatest near the positive charge and least near the negative charge. Equipotential surfaces have equal potentials everywhere on them. For stronger fields, equipotential surfaces are closer to each other! These equipotential surfaces are always perpendicular to the electric field direction, at every point. The electric field is the gradient of the potential. If the equipotential lines are closer together, the potential changes by the same amount over a shorter distance. Consequently, the electric field is stronger in this case. Electric field lines begin on positive charges and radiate away from them toward negative charges, where they terminate. Equipotential lines are lines connecting points of the same electric potential. All electric field lines cross all equipotential lines perpendicularly. The electric field strength is represented by the distance between the equipotential lines. The closer together the equipotential lines are, the stronger the electric field. The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines. Work is needed to move a charge from one equipotential line to another. Equipotential lines are perpendicular to electric field lines in every case. W = −ΔPE = −qΔV = 0. Electric field lines are perpendicular to the equipotential lines, and point "downhill" and a conductor forms an equipotential surface when lines are close to each other, the electric field is strong.
