Abstract
An undergraduate experiment using commercially available low power incandescent lamps was performed. The results
obtained, for higher temperature of the filament (say above 1000 K), were compared with those calculated using a
simple model, based on transfer of electric power predominantly into Planck’s radiation channel through Stefan-
Boltzmann law. The agreement between the results and the theory was quite satisfactory. Measurement of filament
temperature to confirm theoretical results, included in the present work, is expected to give a student more confidence
in the theory.
