It has already been seen that a positively charged body emanates electric lines of force, whereas these lines of force are terminated at the negatively charged body. The total electric lines of force emanated from a positive charge is called electric flux.
Electric flux, in fact, is a measure of the overall size of electric field. It is measured in coulomb (C) and is generally represented by Ψ(psi a Greek letter). Two parallel plates separated by some dielectric medium are shown in Figure 3.7. When one plate is charged with +Q coulomb and the other with − Q coulomb, an electric field is established between them. This field is distributed uniformly. The total electric lines of force or electric flux established between them will be Ψ = Q coulomb.
