"Today we're going to work on a whole new concept and that is the concept of electric flux. We've come a long way. We started out with Coulomb's law. We got electric field lines. And now we have electric flux.
Suppose I have an electric field which is like so and I bring in that electric field a surface, an open surface like a handkerchief or a piece of paper. And so here it is. Something like that. And I carve this surface up in very small surface elements, each with size DA, that's the area, teeny weeny little area, and let this be the normal, N roof, the normal on that surface.
So now the local electric field say at that location would be for instance this. It's a vector..."
