Electrostatic Field Mapping Introduction The purpose of this lab is to draw a map of the electric field produced by a charge  distribution and to compare the results to those predicted by electromagnetic theory. Since  equipotential surfaces are always at right angles to the electric field lines when they cross,  you will be able to draw a map of the electric field lines once the equipotential surfaces  have been drawn.  Experimental Procedures The Electric Field Produced by a Point Charge 1) Set the voltmeter function to DCV and the range to 20. Place the red lead in the hole  marked V/Ω. Place the black lead in the hole marked COM. 2) Tack the conducting paper to the peg board using plastic push pins. Tack the large  conducting ring to the paper using lots of pins. Place a metal pin in the center of the ring.  Push all pins very firmly and check periodically to assure good connections. 3) Touch the red wire of the power supply to the metal pin in the center. Attach the black
