SUMMARY
Electric flux is defined differently depending on the context of the electric field or electric displacement. The first definition states that electric flux is equal to the enclosed charge (Q) within a closed surface, which pertains to the electric displacement field (D). The second definition expresses electric flux as the enclosed charge divided by the permittivity of free space (Q/e), which applies to the electric field (E). Both definitions are correct but are used in different scenarios, highlighting the importance of understanding the distinction between electric displacement and electric field.
