Equipotential Trough Kit, 1 Each

The Equipotential Trough Kit by United Scientific lets students map equipotential lines between two electrodes held at different potentials in an electrolyte solution. It includes a 33 cm x 25 cm plastic trough with a printed grid, strip and rod electrodes, support arms, a sample point arm, a wire harness and a digital multimeter. Physics teachers use it for electric field labs correlated to NGSS MS-PS2-5 and HS-PS2-4.
