Electric current

  1. Apr 7, 2010 #1
    we know that electric current result of motion of electrons through aconductor
    and resistance result of electron's collisions with matter's nuclei resulting in heating material
    my question is what is the effect of positive electric field of nuclei at the motion of negative electrons ?
    isn't there any Probability that the electron fall at nuclei and what may be the result of nuclei electron union ?

    thank you

    Welcome to the PF.

    You will soon learn that the simplistic Bohr model of the atom is incomplete. There are multiple reasons why the "cloud" of electrons around a nucleus do not lose their KE to radiation and fall into the nucleus. Patience, grasshopper.
