1. The problem statement, all variables and given/known data Hello, I am a 6th grade student trying to build a DC motor for the science fair. My hypothesis is that the dc motor will run faster if I place batteries in parallel versus batteries in a series. Is there an equation i can look at to explain what is happening? the mootr will be like the one found on youtube built by howtolou. thank you. 2. Relevant equations 3. The attempt at a solution voltage constant = (V-IR)/rpm???
