K6-23. Hot Dog Cooker - 110 Vac


To illustrate the conversion of electrical energy into heat energy.


Cooker assembly with nails, plastic anti-grease-splatter film to cover hot dog, digital thermometer.

Setup Time

5 minutes. (Instructor must furnish hot dog!!)




A hot dog is mounted as shown in an overhead projection gizzit which skewers the hot dog between two nails connected to 110 VAC. The voltage applied to the hot dog and the current through the hot dog are displayed on the meters. The total energy can be found by plotting a graph of the current as a function of time and integrating. (Actually the current is pretty much constant so you can just take an average.) The initial and final temperatures are read by the digital thermometer.
