# What is the relationship between electric field lines and equipotential lines that you observed in doing the lab?

Contents

Electric field lines begin on positive charges and radiate away from them toward negative charges, where they terminate. 3. Equipotential lines are lines connecting points of the same electric potential. All electric field lines cross all equipotential lines perpendicularly.

## What is the relationship between the direction of the equipotential lines you have drawn?

Equipotential surfaces have equal potentials everywhere on them. For stronger fields, equipotential surfaces are closer to each other! These equipotential surfaces are always perpendicular to the electric field direction, at every point.

## What is the relationship between the density of the equipotential lines the density of the electric field lines and the strength of the electric field?

The electric field is inversely proportional to the density of electric field lines.

## What do you notice about the relationship between charge and electric field lines?

The number of field lines originating or terminating at a charge is proportional to the magnitude of that charge. A charge of 2q will have twice as many lines as a charge of q. At every point in space, the field vector at that point is tangent to the field line at that same point.

## Can two equipotential lines cross?

Equipotential lines at different potentials can never cross either. This is because they are, by definition, a line of constant potential. … If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

## Why electric field is normal to equipotential surface?

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.

## Which statement is true for electric field lines?

Electric field lines do not form any closed loops. The statement is true because the electric field lines start from positive charge and end on negative charge. Since the starting and ending point of the electric field lines is different, a loop can never be closed.
