25. Electric Potential

A surface will be an $\mathrm{equipotential}$ surface if which of the following conditions is satisfied?

Draw the electric field that corresponds to the equipotential surfaces shown in the following figure. Note that the potential is decreasing in the upward direction.

If the $equipotential$ surfaces in a region are spaced closer together in one area and farther apart in another, what does this indicate about the strength of the $electric$ field in those regions?

Which of the following statements correctly describes an equipotential surface?
