Homework Statement



Im starting to read about the electric flux and gauss's law. Im reading two books, Serway and Schaums electromagnetics.

The weird thing is that I'm getting different equations for the electric flux

Serway says that the Electric flux ψ is ∫E ds = 1/ε ∫ρ dv = Q/ε

While in other books I found that The Electric flux ψ is ∫ρ dv = Q

What is the real Electric flux equation ?

Thanks a lot.

In Schaum's, is the flux ψ defined in terms of the field E or the field D?

it is defined in terms of D

as ∫D ds = Q = ψ

Ok, that should account for the difference if you look at the relationship between E and D.
