# Frequent question: What do electric field lines represent?

Contents

Electric field lines reveal information about the direction (and the strength) of an electric field within a region of space. If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location.

## How do electric field lines indicate the strength of the field?

The strength of the electric field depends on the source charge, not on the test charge. … A line tangent to a field line indicates the direction of the electric field at that point. Where the field lines are close together, the electric field is stronger than where they are farther apart.

## What is the purpose of field lines?

They are used to show electric fields, magnetic fields, and gravitational fields among many other types. In fluid mechanics field lines showing the velocity field of a fluid flow are called streamlines.

## What two things do field lines indicate?

Since a field line represents the direction of the field at a given point, if two field lines crossed at some point, that would imply that the electric field was pointing in two different directions at a single point.

## How do electric field lines indicate the strength of the field by how long the lines are by how close the lines are?

The strength of the field is proportional to the closeness of the field lines—more precisely, it is proportional to the number of lines per unit area perpendicular to the lines. The direction of the electric field is tangent to the field line at any point in space. Field lines can never cross.

## How do electric field lines indicate the strength of an electric field quizlet?

How do electric field lines indicate the strength of an electric field? the space that surrounds electrically charged particles. The closer you get tp a charge, the stronger it gets. … The repulsion of the like charges creates a space (Gap X) between their electric fields.

## What do you mean by electric field lines write the properties of it?

An electric field line is an imaginary line or curve drawn from a point of an electric field such that tangent to it (at any point) gives the direction of the electric field at that point. Properties : 1. Electric field lines starting from positive charge and terminating at a negative charge.

## What are electric field lines Class 12?

Electric field lines are a pictorial way of representing electric field around a configuration of charges. An electric field line is a curve drawn in such a way that the tangent to it at each point is in direction of the net field at that point.

## Why do electric field lines come from positive charge?

The electric field is a vector field around a charged particle. It represents the force that other charged particles would feel if placed near the particle creating the electric field. … If the point charge is positive, field lines point away from it; if the charge is negative, field lines point toward it.

## What does the relative density of electric field lines represent?

Answer: Field lines give us information about the direction of E, but also about its. magnitude, since the relative density of field lines is a measure of the relative. strength of the electric field.

## Why do electric field lines never cross?

Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

## How do you define a field line?

Noun. 1. field line – an imaginary line in a field of force; direction of the line at any point is the direction of the force at that point. line of force. line – a spatial location defined by a real or imaginary unidimensional extent.

## Where are electric field lines strongest?

Field-Line Patterns

The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest.

## At which point is the electric field the strongest *?

The magnitude of an electric field is directly proportional to the density of electric field lines. When the lines are closer to each other, the >electric field is the strongest; when the filed lines are far apart from each other, the electric field is the weakest.

## At what point is the electric field the strongest?

The field is strongest where the lines are most closely spaced. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.
