Question

Electric flux is equal to select one: a. None of the above b. Charge c. Charge density d. Current

Answer 1

Answer:

None of the above

Explanation:

Electric flux is equal to the rate of flow of electric field per the given area. Electric flux is equal to the number of field lines passing through a virtual surface

Electric flux is given by the formula dot product of electric field and the given area.

Let us consider electric flux as Ф.

Let the electric field in the region be E

Let the area along which the flux needs to be measured or the area of the surface be A.

Then electric flux through the region is given by

Ф=E.A

Ф=EAcosβ

Where β is the angle between the electric field lines and the area of the surface.

Even if we consider  dimensional analysis for that of electric flux according to the above mentioned formula it will not be equal to charge, charge density and current, therefore the correct option is none of the above, which is the required answer.
