Electron Current vs. Conventional Current
Electron Current vs. Conventional CurrentIn 1752, prior to electricity being identified with the Electron , ben franklin chose a convention re-garding the direction of Current flow. franklin assumed that positive charge carriers flowed frompositive to negative terminals. We now know this is incorrect. In metals, the charge carrier is theelectron whose charge is negative by definition (note negative sign): ( 10 19C)The flow of electrons is termedelectron Current . Electrons flow from the negative terminal to currentor simplycurrent, behaves as if positive charge carriers cause currentflow. Conventional Current flows from the positive terminal to the negative. Perhaps the clearestway to think about this is to pretend as if movement of positive charge carriers constituted Vcurrent owelectron owcurrent owelectron owFigure 1: Electron Flow and Conventional Current FlowIt is important to realize that the difference between Conventional Current flow and Electron flowin no way effects any real-world behavior or computational results.
