Chukwuemeka Iloka Due Date: 4/16/2020 Lab H: Electrical Equivalent of Heat Objectives 1. To determine the electrical equivalent of heat, the conversion factor between the electrical energy unit, joule, and the heat energy unit, calorie. 2. To come to a deeper understanding of Conservation of Energy. Background According to the law of conservation of energy, the total amount of energy in an isolated system remains constant over time. On the other hand, energy cannot be created or destroyed, but can be transformed from one form to another. For example, electrical energy can be transformed to heat energy. In this experiment we will heat water using an electric heating coil with current running through it. When current is running through the coil the total electrical energy dissipated to the coil is represented by the equation E = Pt where t is the time during which the current flows through the coil and P is the electrical power in watts. Power is given by P=IV where I is the current in amperes and V is the voltage.
