Equipotential Trough Kit

Plot equipotential lines accurately with water and a digital multimeter.

• Plot equipotential lines for various electrode configurations
• Classic design
• Correlates to NGSS Standards MS-PS2-5 and HS-PS2-4
• Activity guide included

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.
