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.
