Electric Fields Lab Abstract: In this lab we will study the equipotential lines in an electric field in order to study the structure of the electric lines of force. We will plot the position of electric field lines in a given electric field using both a manual method and a computer software program. There is an electric field in any region where there is a force on an electric charge at rest. It is convenient to represent an electric field
