Lab 2 Electric Potential & Electric Fields
Abstract
This experiment was performed with the purpose of finding and plotting the electric field vector components
across a two-dimensional surface. The electric potential data was obtained for every corresponding (x,y) point
and converted into a list by using the (DAQ). The surfaces tested with the measuring probe consisted of four
uniform shapes which include the following: Dipole, point plate, sphere, sharp point, and additional diamond
custom shaped surface. Additionally, the voltage probe attributed high electrical potential differences from the
points in the surface with respect to the ground and assigned the color red. Lower potential differences were
assigned the blue color and a “thermo” map was able to be generated from these program specifications.
