# What is an equipotential surface Why is electric field always 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.

## What is equipotential surface of the system?

Equipotential surfaces are the regions where the electrostatic potential due to charges at every point remains same. Equipotential surfaces are always perpendicular to the electric field so the work done in moving a test charge between two points on an equipotential surface is zero.

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

equipotential surfaces any surface with same electric potential at every point is called an equipotential surface. In this case the “altitude” is electric potential or voltage. Equipotential lines are always perpendicular to the electric field.

## What is the relation between electric field and electric potential?

The relationship between potential and field (E) is a differential: electric field is the gradient of potential (V) in the x direction. This can be represented as: Ex=−dVdx E x = − dV dx . Thus, as the test charge is moved in the x direction, the rate of the its change in potential is the value of the electric field.

## Why are electric field lines not discontinuous?

An electrostatic field line cannot be discontinuous. … The force experienced or the path followed by charge cannot be discontinuous and hence the lines are not broken. Also, electrostatic field lines represent the electric field strenth and the strength of field is never broken.

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

The mutual repulsion of excess positive charges on a spherical conductor distributes them uniformly on its surface. The resulting electric field is perpendicular to the surface and zero inside.

## What is equipotential surface answer?

What is Equipotential Surface? 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.

## What is the 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.

## Why is electric field always normal to equipotential surfaces?

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.

## What is an equipotential surface show that the electric field is always?

(A) The circumference of the flat surface is an equipotential.

## What is equatorial 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.

## What is the relationship between the electric field and the electric potential between the plates of the capacitor?

The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates.

## What is the relationship between the electric field E and electric potential V between the plates of the capacitor?

The relationship between V and E for parallel conducting plates is E=Vd E = V d .

## What is the relation between electric field and electric potential class 12?

The electric field E due to a point charge at a point is the force F per unit charge acting on a charged body of charge q placed at that point. The electric potential due to a point charge is the external work done to move a unit charge against the electric field by an infinitesimal distance without any acceleration.
