Technical data Electrical power and work with Cobra SMARTsenseArticle no: P1373369 ![]() Principle The electrical power required to operate electrical components results from the electric current flowing at an applied voltage. In this experiment, the brightness of incandescent lamps is used as a measure of electrical power. Students can easily see, for example, that two identical lamps together have twice the power if they shine with the same brightness. Benefits
Tasks Using the parallel and series connection of incandescent lamps, investigate the dependence of electrical power on current and voltage. Learning Objectives Students will be able to deduce the relationship between power and amperage and voltage from the experiment: P ∼ U for I = constant and P ∼ I for U = constant. Scope of delivery
