# Question: What is an equipotential surface so that the electric field is always directed perpendicular to an equipotential surface?

Contents

An equipotential surface is circular in the two-dimensional. Since the electric field lines are directed radially away from the charge, hence they are opposite to the equipotential lines. Therefore, the electric field is perpendicular to the equipotential surface.

## Why the electric field is always directly perpendicular to an equipotential surface?

this is because there is no potential gradient along any direction parallel to the surface , and so no electric field parallel to the surface. This means that the electric lines of force are always at right angle to the equipotential surface.

## Why electric field is perpendicular to equipotential surface draw equipotential surfaces for i uniform electric field II electric dipole?

Work done in moving a charge from one place to another on an equipotential surface is zero, Electric Field is always perpendicular to an equipotential surface, so a same system of charge there can be many equipotential surfaces but two equipotential surfaces never intersect each other, and they should be drawn such …

## What is meant by equipotential surface?

The surface which is the locus of all points which are at the same potential is known as the equipotential surface. … In other words, any surface with the same electric potential at every point is termed as an equipotential surface.

## Why are electric field lines perpendicular to the surface of a conductor Class 12?

So that the electrostatic field inside the conductor is zero. In the static situation, no excess charges will be present inside the conductor. … To get equipotential or constant potential throughout the surface, electrostatic field lines have to be perpendicular to the segments of the conductor.

## What is equatorial surface?

Any surface over which the potential is constant is called an equipotential surface.In other words, the potential difference between any two points on an equipotential surface is zero. Some important properties of equipotential surfaces : 1. Work done in moving a charge over an equipotential surface is zero. 2.

## What are the equipotential surfaces of a point charge?

For a point charge, the equipotential surfaces are concentric spherical shells. The direction of the equipotential surface is from high potential to low potential. Inside a hollow charged spherical conductor the potential is constant.

## What is angle between electric field and equipotential surface?

The angle between the electric field and the equipotential surface is always 90. The equipotential surface is always perpendicular to the electric field.

## What is an equi potential surface show that the electric field is always directed perpendicular to an equi potential surface?

An equipotential surface is circular in the two-dimensional. Since the electric field lines are directed radially away from the charge, hence they are opposite to the equipotential lines. Therefore, the electric field is perpendicular to the equipotential surface.

## What is an equipotential surface give example?

a surface all of whose points have the same potential. 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.

## What is an equipotential surface write its characteristics?

The characteristics of an equipotential surface are: Potential remains the same at all the points on equipotential surface. No work is required to move a charge on an equipotential surface. No two equipotential surfaces can ever intersect each other.

## Is the electric field always perpendicular to the surface?

Equipotential surfaces have equal potentials everywhere on them. … These equipotential surfaces are always perpendicular to the electric field direction, at every point.

## Why electric field lines are always normal to the surface of a conductor?

Electric field is defined as the gradient of potential and the surface of a conductor has a constant potential. Therefore, there is no field along the surface of the conductor and hence the electrostatic field at the surface of a charged conductor should be Normal to the surface at every point.

## When the electric field vector is perpendicular to the surface?

If the surface is perpendicular to the field (left panel), and the field vector is thus parallel to the vector, →A, then the flux through that surface is maximal. If the surface is parallel to the field (right panel), then no field lines cross that surface, and the flux through that surface is zero.
