Electron Current vs. Conventional CurrentIn 1752, prior to electricity being identiÞed with the electron, Ben Franklin chose a conventionregarding the direction of current ßow. Franklin assumed that electrons (being assumed positive)ßow from positive to negative terminals. We now know this is incorrect. The charge on an electronis negative by deÞnition (note negative sign): (-1.6x10The ßow of electrons is termedelectron current.
