3/9/08 Lab LN Group 2 Electric Field and Electric Potential Introduction The main purpose of this lab was to observe the relationship between the electric field and the electric potential. We looked at two different types of electric fields, one created by two point charges and another by two conducting rods. In the first part of the lab we used a volt meter to trace the electric field between two point charges. We did so by taking measuring the field strength at 12, equal spaced, points along the plane of the point charges. We then found other points of the same values that corresponded to those positions and connected the dots. In part two of the lab we followed the exact same procedure only with the conducting bars instead of the point charges. By finding the electric field we can then find the electric potential around the points. We can do this because we know that E = - V Where E is the electric field, is the gradient operator and V is the electric potential. This tell us that the electric potential will be perpendicular to the electric field at equal values. We can also find the magnitude of the electric field by E = ∆V∆s Where ∆s is the change on the distance between electric potential lines. Data Analysis
