Instructions
Take a plastic tray with the dimensions of 8 inches by 12 inches and make sure it is several inches deep. Use a sheet of plastic imprinted with waterproof ink that has evenly spaced graph grids. Put the plastic graph sheet on the bottom of the plastic tray and fill the tray with water.
Determine the magnitude of the electric field at any given point on the submerged plastic graph. A given point (P) on the plastic graph paper is known, but to test the electric field vector, determine the level of charge (a charge q) that is present in the water at any given point on the plastic graph sheet. This is known as the force of an electric field in the water. This is accomplished by gathering results from a digital multimeter and 25-V AC transformer.
Connect each of two leads to a different terminal of the 25-V AC transformer. Connect the black lead of the digital multimeter to one terminal of the transformer. Insert the red lead into the tray of water to measure the electric vector potential of the water at different points on the plastic graph. This constant charge of the 25-V AC transformer in relation to the charge of the water will determine the water's electrical potential at different points. The equilibrium of the charge is disturbed and the differences are measured by the digital multimeter.
