Electric flux definition confusion

  1. Aug 7, 2008 #1
    Help. I am confused. I have read two different infos in different text books. I have read the topic about electric flux in different books. The first book says that electric flux is simply the Q (charge)in an enclosed surface, on the other hand, the other book says that electric flux is the Q/e(epsilon) in an enclosed surface. Which is correct? I have sought other different books but still it showed me these different ideas.

    The first case, for which the flux through the closed surface is Q, is the flux of D, the electric displacement, whereas the second one is for E the electric field.
