In Search of the Dimensions of an Incandescent Light Bulb Filament
Ladino, Luis A.; Rondón, Hermilda S.
Physics Education, v53 n3 Article 035018 May 2018
The purpose of this paper is to present and discuss an alternative solution to an experimental problem given to high school students in the XXII Ibero-American Physics Olympiad held by Colombia this year. From the measurements of electric current and potential difference across a small tungsten filament lamp students should find the dimensions of its filament. The results obtained are compared with the ones measured directly. This challenging and low-cost experiment can be easily implemented and carried out in any introductory physics laboratory courses.
