Background: When connected to a power supply, the pre-made carbon paper sheets with conductive traces will have invisible electric field lines that flow from the positive rail to the negative rail. The separation between E-Field lines drawn represent the electric field intensity. Remember: like magnetic fields, E-Fields flow from positive to negative and never cross! Procedure: 1. Connect the power supply to the two conductive traces of the carbon paper sheets and set the voltage to 5.00 V. 2. Set the voltmeter to 20 V and connect the black probe to the negative conductive trace on the carbon paper. 3. On a separate worksheet, draw the two conductive rails, then map the field by touching the positive red probe at every single crosshair on the conductive paper and take note of the potential difference at each crosshair. Observations & Analysis: 1. Connect all cross-hairs of equal voltages (or equal potential) by drawing curves of best-fit on your worksheet. Trace at least ten equipotential lines within the space of the two conductive traces 2. Using a different colour than the one you used to draw your equipotential lines, draw several e-field lines that leave from the positive conductive rail and cross through each equipotential line at 90°. These lines should terminate at the negative conductive rail. Don't forget to include arrows to indicate direction of each e-field line. 3. What would happen to the field diagram if the voltage of the power supply was increased?
