The total electric flux coming out from a closed surface enclosing a stationary
unit positive charge in air is
Answers
Answer:
Electric flux is the rate of flow of the electric field through a given area.
Electric flux is the rate of flow of the electric field through a given area (see ). Electric flux is proportional to the number of electric field lines going through a virtual surface.
