Question

what do you mean by equipotential surface? ❤​

Answer 1

Answer:

The surface which is the locus of all points which are at the same potential is known as the equipotential surface. No work is required to move a charge from one point to another on the equipotential surface.

Equipotential Points: If the points in an electric field are all at the same electric potential, then they are known as the equipotential points. If these points are connected by a line or a curve, it is known as an equipotential line. If such points lie on a surface, it is called an equipotential surface. Further, if these points are distributed throughout a space or a volume, it is known as an equipotential volume.

For example, the surface of a conductor in electrostatics is an equipotential surface. In a force field the lines of force are normal, or perpendicular, to an equipotential surface.

Answer 2

Equipotential Surface

Any surface having equal potential everywhere is called as equipotential surface.

Example- A sphere with a charge at its centre is an equipotential surface.

Properties of Equipotential surface

1. The work done in moving a charge between any two points on an equipotential surface is always 0.
2. Electric field is always perpendicular to equipotential surface.
3. Two equipotential surfaces can never intersect each other. Since, if they do so, there will be two direction of electric field at line of intersection which is not possible.
4. The relative closeness of equipotential surfaces give an idea of intensity of electric field in that region. Closer the equipotential surfaces, greater is the intensity of electric field.
