Explanation

Electric flux is measured in Coulombs C, and surface area is measured in square meters (m2).

The SI unit of electric flux density is coulomb per square meters (C/m2).

Explanation

The transmission line feeding power on either side of the main transmission line is called Secondary transmission.

Explanation

The capacitance between two parallel charges sheets is dependent upon surface area and distance between the plates.

Capacitance of a parallel plate capacitor depends on the dielectric constant of the medium between the plates, area of each plate and distance between the plates.
