Energy mass x latent heat
WebViews: 5,652. In an X-ray tube, electrons are accelerated through a potential difference of 75kV. The electrons then strike a tungsten target of effective mass 15g. The electron energy is converted into the energy of X-ray photons with an efficiency of 5.0%. The rest of the energy is converted into thermal energy.
