You will plot equipotential lines lines of equal electric potential and sketch in lines representing the electric field between the electrodes. Every electrically charged object produces an electric field around it at all points in space — similar to the way an object with mass produces a gravitational field around it at all points in space — affecting all other surrounding charged objects. Thus, we can express the electric field produced by a single point charge as:. Therefore, electric field lines radiate away from positive charges and terminate at negative charges. Because the electric field has both a magnitude and a direction, it is known as a vector field. This electric field surrounding charged objects is therefore analogous to the gravitational field surrounding all massive objects.

To show the effectiveness of chemical treatment in a water treatment facility. To evaluate coagulation efficiency. To determine the most effective dosage of the recommended coagulants and flocculants. To selects the best chemical or best dosage to feed on the basis of clarifies of effluent and minimum cost of chemicals. To gain a hands on understanding of the treatment process for removing suspended solids from water. Colloidal particles are in the size range between dissolved substance and suspended particles. The particles are too small to be removed by sedimentation or by normal filtration processes.
