Ina uniform electric field, field lines and equipotentials
Answers
Answer:
Equipotential lines are like contour lines on a map which trace lines of equal altitude. In this case the "altitude" is electric potential or voltage. Equipotential lines are always perpendicular to the electric field. In three dimensions, the lines form equipotentialsurfaces.
Explanation:
Uniform field means a constant field at every point and it is directed in a fixed direction for all points. Thus equipotential surfaces must be plane surface. The electric field is always perpendicular to equipotential surface because E=−∇V. As surfaces are equipotential so it must be spaced such that surfaces having equal differences in potential are separated by equal distances. As E=−drdV so it must have decreasing potentials in the direction of the field.
