Introduction

Summary

Principle of superposition: The total electrical field at a point is the vector sum of the fields at this point due to each point charge. One can make the lines of force appear with a simple mouse click.

Goals

• To reveal the symmetry of the electric field created by two single charges.
• To explain the link between the field vector at a point and the lines of force at this point.
• To see at every point how the principle of superposition acts.

Features

Click on the screen to make the lines of force visible.
