Electric Field Plotting I Objective: The objective of this lab was to investigate the nature of electric fields formed by two parallel line conductors and two dipoles using a digital voltmeter. Electric field lines always start on positive charges and end on negative charges. In the case the parallel line conductors, the field lines should run straight down vertically from the top line to the bottom line, on the edges of the plates, the field lines would curve. In the case of the dipoles, the lines should start on the positive pole and end on the negative pole, there should be one straight field line right down the middle, but rest of the field lines would be parabolic curves. There should also be equipotential lines, formed by points that have no voltage difference between them. These equipotential lines are always perpendicular to the field lines. The magnitude of the electric field (E) is also related to the voltage change by the equation E=- V/ d. So it is possible to determine the magnitude of the electric field by plotting voltage versus the distance away from one plate, the slope of the line will be E. Another method of finding E is to manually pick two points close to each other, find the voltage difference between them and divide it by the distance. Procedure:
