Lab Course 103A -Section 006 Physics Laboratory Report Lab number and Title: Lab H: Electrical Equivalent of Heat Name: Nicholas Ramirez Group members: Carlos Skerrett, Gerome Garses, Shail Sheth, Conor Mccan, Erin Heidleberger Experiment Date : 3- 31-17 Instructor’s name: Sizhan Liu 1. OBJECTIVES To determine electrical equivalent of heat (Je), the conversion factor between the electrical energy unit, joule, and the heat energy unit, calorie. And to come to a deeper understanding of Conservation of Energy. 2. THEORETICAL BACKGROUND According to the law of conservation energy, the total amount of energy in an isolated system remains constant over time. One the other hand, energy cannot be created or destroyed, but can be transformed from one to another. For example, electrical energy can be transformed to heat energy. Suppose that there is an insulated container containing a certain amount of water, called a system. The system is heated by submerging a heating coil in the water and running an electric current through the coil. When the heating coil and electric current is running through it, the total electrical energy E dissipated to the coil is:
