"Thermal energy" situations exist everyday in our homes, but we don't call them "thermal energy" applications. We call them baking, cooking, or turning up the house heater. Let's look at a small hair dryer that draws 10A of current under a typical household 120V voltage. What is the power rating of the hair dryer in watts? Depending on the application, the time unit of minutes or hours are preferred over the time unit of seconds often used in physics. Utility companies use kilowatt-hour units for energy rather than the watt-second units. These units are more practical given how much energy a home uses. Let's say you run the hair dryer 6 minutes to dry your hair. How much energy was used in Watt-hour units? What is this energy in kilowatt-hours (kWh) ? Electricity is not free. Someone pays the electric utility bill so you can run the hair dryer, heat the home, cook and bake. The average electricity rate in the U.S. is about 10 cents per kilowatt-hour. (By the way, the state of…
