Sobre este recurso...

AAA, AA, C, D batteries all are rated at 1.5 volts but besides the difference in physical size theamount of electric current they produce is also different. In this project the four battery types will be connected to a small hobby motor designed to operate with a 1.5 volt D size battery and a specific current. From the observations madea data table will be produced and the results will be displayed in the form of a graph.If the batteries all have the same voltage, why not just use AAA cells for all battery operated devices?Let's find out.What are the operating differences of AAA, AA, C, D batteries all with a 1.5 volt rating?Why will an electrical device that requires a 1.5 volt D size battery not operate as well with a 1.5 volt AA size battery?
