You might think we love pink, purple and blue, judging by our website. If an equal current flows in a wire of the same material but of twice the radius,what is the new mean drift. It is measured in amperes. If the wire is connected to a 1. View Homework Help - chapter 7 HW from PHYS 102 at Embry-Riddle Aeronautical University. Do electrons flow from positive to negative? Or do they flow from negative to positive? This AddOhms tutorial looks at the difference between Conventional Flow and Electron Flow. This chapter will introduce the polarities and current direction associated with DC circuits.
