Objective:To determine electrical equivalent of heat (Je), the conversion factor between theelectrical unit of, joule, and the heat unit, calorie; to come to a deeper understanding ofConservation of Energy.Theory:According to the law of conservation of energy, the total amount of energy in an isolated systemremains constant over time. On the other hand, energy cannot be created or destroyed, but can betransformed from one form to another. For example, electrical energy can be transformed to heatenergy. Suppose that there is an insulated container (calorimeter) containing a certain amount ofwater, which is called a system. The system is heated by submerging a heating coil in the waterand running an electric current through the coil. When the heating coi is connected to an electric
