Stepfans Law Trainer
SPECIFICATION
55940 Verification of Stefan's Law illustrates the basic phenomenon of thermodynamics. The Trainer gives an idea of how energy loss depends on temperature. Stefan's Law states that the power radiated by a body is proportional to the 4th power of the absolute temperature. The phenomenon can be studied using a light-bulb filament used as radiating body. The power can be determined from the voltage and current of the filament. The temperature of the filament can be determined indirectly by first computing the electrical resistance and then using a standard resistance versus temperature relationship.
