PHYSICAL
MEANING OF ELECTRIC FLUX
|
||||
|
|
In physical sense, electric flux is defined as: |
|||
|
"The total number of lines of force passing through the unit area
of a surface held perpendicularly."
|
||||
|
MATHEMATICAL
MEANING OF ELECTRIC FLUX
|
||||
| Mathematically the electric flux is defined as: | ||||
| "The dot product of electric field intensity (E) and the vector area (DA) is called electric flux." | ||||
 Where q is the angle between E and DA |
||||
|
MAXIMUM
FLUX

|
If
the surface is placed perpendicular to the electric field then maximum
electric lines of force will pass through the surface. Consequently maximum
electric flux will pass through the surface.

|
ZERO
FLUX
|
||||
| If the surface is placed parallel to the electric field then no electric lines of force will pass through the surface. Consequently no electric flux will pass through the surface. | ||||
 |
 |
|||
| Flux is a scalar quantity . | ||||
