The misconceptions about the calculation of light bulb resistance in specialized school

G. Movsum Oghlu Sharifov

Abstract


The paper deals with the study of the resistance of incandescent light bulbs. It has been established that the temperature dependence of resistance for these types of lamps always manifests itself in school experiments. Therefore, students in specialized school should be taught a systematic comparison of resistance in resistors and lamps in circuits in term of didactic principles and be given a detailed explanation of the different factors that occurred in lamp circuits and were mistakenly understood as equipment errors.


Keywords
