Question

Q. Define electric flux :-​

Answer 1

Answer:

Total number of lines of force passing through an area immersed in an electric field (E) is known as flux. The electric flux through a surface is defined as the product of the area (s) and the component of the electric field normal to the surface (En), e.i.= En*S.

Electric flux through a closed surface will be positive or negative depending on whether the field lines emerge from the surface or enter into the surface.

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.

If the electric field is uniform, the electric flux (ΦE) passing through a surface of vector area S is: ΦE = E⋅S = EScosθ, where E is the magnitude of the electric field (having units of V/m), S is the area of the surface, and θ is the angle between the electric field lines and the normal (perpendicular) to S.
