Those having only magnitude but no direction are known as scalar quantity. Time, mass, work, power, electric current, electric charge, moment of inertia, magnetic flux, electric flux and so many are found to be scalar in this world.
Surface deliberately made to ease the calculation of the electric flux for detemination of Electric field from gauss's law.
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
Types of flux - Electric and Magnetic Flux. Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.
The unit of electric flux is Volt-meter or Newton-meter^2 Coulomb^-1.

The electric flux depends on charge, when the charge is zero the flux is zero. The electric field depends also on the charge. Thus when the electric flux is zero , the electric field is also zero for the same reason, zero charge. Phi= integral E.dA= integral zcDdA = zcQ Phi is zcQ and depends on charge Q, as does E.
Luminous flux is measured in lumens (symbol: lm).
Reluctance is the opposition offered by a magnetic circuit to the formation of magnetic flux. The symbol for reluctance is R or Rm. Reluctance is measured in amperes per weber (A/Wb). Reluctance is equivalent to resistance in an electric circuit.
In case of electrostatics, flux density = electric field intensity and in case of magnetism, flux density = magnetic field induction
Under an electric field, magnitude and direction of electric intensity is different in every point.If the electric intensity can be defined through a closed line (direction of electric intensity will be along the tangent of any point of that line)this is called electric lines of force. Electric lines of forces passing through an closed electric surface perpendicularly, is called electric flux.
