Once we know the equipotentials, we can construct the corresponding electric field lines, giving us an informative visual display of the field. A. Equipment 3 Carbonized Acetate Sheets (“parallel plate”, “dipole”, and “dipole plus circle”), 1 dry cell (1.5V), 1 Digital Voltmeter, Galvanometer, 2 Voltage probes. B. Method Each carbonized sheet has a certain pattern of highly conducting areas silver-painted onto it. These painted areas are connected to the terminals of the dry cell which supplies charge to the conductors and maintains a constant potential between them. A current flows through the resistive carbon film from one conductor to the other. By probing the area between the conductors with the digital voltmeter, we will find sets of points that have zero potential difference
