The potential difference applied to an X-ray tube is 5 kV and the current through it is
3.2 mA. Then the number of electrons striking the target per second and speed at which they strike?

  • physics -

    electrons/sec = I/e

    Electron energy E = e*V

    Electron velocity = sqrt(2E/m)

    e = electron charge
    m = electron mass
