This comprehensive kit allows students to plot equipotential lines in an electric field between two electrodes held at different electric potentials. A simple setup keeps electrodes partially immersed in water containing an electrolyte, allowing a small current to flow between the electrodes. Students can then sample the resulting electric field using the included multimeter. Contents: Plastic trough, 33cm x 25cm, with printed orientation grid and fitted with three electrode support posts Wire harness with snap connector and two alligator clips 2 straight metal strip electrodes, 10cm long 2 short rod electrodes 2 electrode support arms Sample point arm Digital multimeter Activity guide
