Computer Enhanced Electrics Fields Experiments
Abstract
A new quantitative experiment is described for plotting electric fields using a computer data acquisition system and an X-Y digitizing tablet. The experiment measures the equipotential points on a sheet of conductive paper on which electrodes have been placed with silver paint. Voltages are measured with a digital-to-analog converter and X-Y coordinates are determined with a commercial X-Y digitizing tablet. The X-Y coordinates can be determined with the conducting sheet randomly oriented on the X-Y digitizing tablet. Data are recorded and plotted in a spreadsheet for analysis. A control and measurement program written in VisualBasic for Windows controls and facilitates the acquisition, recording, and analysis of data. The apparatus and experiment will be described and demonstrated.
