# What are equipotential lines in electric field?

Contents

## How is the electric field related to the equipotential lines?

An electric field is a region in space where one charge experiences a force from another charge. … Equipotential lines are lines connecting points of the same electric potential. All electric field lines cross all equipotential lines perpendicularly.

## How do you calculate the electric field?

We can find the electric field created by a point charge by using the equation E=kQr2 E = k Q r 2 .

## What is the angle between the electric field vector and equipotential lines?

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 the visual relationship between equipotential lines and electric field lines?

Electric field lines are always perpendicular to equipotential lines. This includes the surface of a conductor. Electric field lines never cross and equipotential lines never cross. Electric field lines start on positive charges and end on negative charges.

## How is the field strength related to the equipotential surfaces?

Since the equipotential lines are perpendicular to the electric field, moving a test charge along an equipotential surface requires no work because the electric force is perpendicular to the motion. … Thus, the electric field is strongest where the equipotentials are closest together.
