“Map” the Electric Field Between Two Electrodes Painted onto Conductive Paper
First paint any electrode configuration you wish onto the special conductive paper with silver paint. Then connect the electrodes to the supplied battery holder.
The battery sets up a current in the paper which generates voltages at all points on the paper. You measure these voltages at many points using a multimeter and a metal probe to touch the paper where you want to measure. On a separate sheet of paper, you record the voltage locations.
This kit includes cork-covered base, 30cm x 26cm; pad of 25 sheets pre-printed conductive paper 28cm x 21.5cm; pad of 100 sheets pre-printed paper for drawing fields; nine metal-headed push pins; a silver conductive pen; four alligator clip leads; circle template and instruction sheet.
Requires D-Size Battery and Battery Holder or DC Power Supply, and a Multimeter (sold separately).
