## What can you conclude about the equipotential lines of an electric dipole?

Equipotential lines: dipole The electric potential of a dipole show mirror symmetry about the center point of the dipole. They are everywhere perpendicular to the electric field lines. The plane perpendicular to the line between the charges at the midpoint is an equipotential plane with potential zero.

**What is the relationship between electric field lines and equipotential lines?**

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 can you conclude about the direction of the electric field vector in relation to the equipotential lines?

Equipotential lines are lines with equal electric potential (for example, all the points with an electric potential of 5.0 V). What can you conclude about the direction of the electric field vector in relation to the equipotential lines? The direction for each field vector is perpendicular to equipotential lines.

**Why do field lines intersect equipotential lines and conductive surfaces at right angles?**

If a small test charge is moved so that its direction of motion is always perpendicular to the electric field at each location, then the electric force and the direction of motion at each point are perpendicular. Therefore, electric field lines and equipotentials always cross at right angles.

## What do you mean by electric field lines?

An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.

**Where is the electric field strongest equipotential lines?**

Thus, the electric field is strongest where the equipotentials are closest together. This is analogous to the steepness of a slope on a contour map: the slope is steepest where the contour lines are closest.

### How do you find electric field lines?

E = F q test = k | Q | r 2 . This equation gives the magnitude of the electric field created by a point charge Q. The distance r in the denominator is the distance from the point charge, Q, or from the center of a spherical charge, to the point of interest.

**What do electric field lines represent?**

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.

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

The angle between Electric field and an equi-potential surface is always 900. This is because,when the potential becomes constant,the negative potential gradient also becomes zero,hence necessitating the need for Electric field to be always normal with surface.

**What is a general rule about the direction electric field lines point?**

The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge.

### How do electric field lines work?

These pattern of lines, sometimes referred to as electric field lines, point in the direction that a positive test charge would accelerate if placed upon the line. As such, the lines are directed away from positively charged source charges and toward negatively charged source charges.

**What are the three rules for drawing electric field lines?**

1 Answer

- 1) Electric field lines are always drawn from High potential to.
- 2) Two electric field lines can never intersect each other.
- 3) The net electric field inside a Conductor is Zero.
- 4) Electric field line from a positive charge is drawn radially outwards and from a negative charge radially inwards.

## What are the objectives of the equipotential line experiment?

Experiment 1: Equipotential Lines and Electric Fields OBJECTIVES 1. To develop an understanding of electric potential and electric fields 2. To better understand the relationship between equipotentials and electric fields 3. To become familiar with the effect of conductors on equipotentials and E fields PRE-LAB READING INTRODUCTION

**How are electric fields and equipotentials related?**

Now consider the relationship between equipotentials and fields. At any point in the potential landscape, the field points in the direction that a mass would feel a force if placed there (or that a positive charge would feel a force for electric potentials and fields).

### How to find equipotential lines in a landscape?

For each of the two landscapes that you choose, you will find at least four equipotential contours by searching for points in the landscape at the same potential using the voltage sensor. After recording these curves, you will draw several electric field lines, making use of the fact that they are everywhere perpendicular to equipotential contours.

**Why does force point across an equipotential line?**

So the force (and hence field) must point across them, pushing the object downhill. But why exactly perpendicular? Work done on an object changes its potential, so it can take no work to move along an equipotential line. Work is given by the dot product of force and displacement.
