The electric field intensity of a point due to a number of a charge is equal to the vector sum of an electric field intensity of individual charge. The number of electric lines of force passing through an area held perpendicularly is called electric flux.
What is the relation between electric intensity and flux Class 12?
Answer: The vector sum of the electric field intensity of individual charges equals the electric field intensity of a point due to a number of charges. Electric flux is the number of electric lines of force travelling through a perpendicularly held region.
What is the relation between electric field intensity E and electric flux density D )?
So, Electric Flux Density, D, is the Electric Field Intensity, E, multiplied by the permittivity of the corresponding medium. It is another way to represent the strength of the Electric Field independent of the medium. It is also a vector quantity exactly the same as E.
Is electric flux and electric intensity the same?
While the strength of the electric field at any point in space is called electric field intensity. It is a vector quantity. Its unit is NC¯¹.
What is difference between electric field and electric field intensity?
|Location||Electric field (N/C)|
|Inside the copper wire of household circuits||10–2|
What is the relationship between electric field intensity current density?
For an amazingly wide range of materials, an empirical rule called Ohm’s law gives the following relation between current density and applied electric field: J = σ E . In other words, the current density is directly proportional to the electric field.
What is the formula for electric field intensity?
The electric field intensity at a point is the force experienced by a unit positive charge placed at that point. Electric Field Intensity is a vector quantity. It is denoted by ‘E’. Formula: Electric Field = F/q.
What is the relationship between E and V?
The relationship between V and E for parallel conducting plates is E=Vd E = V d .
What is difference between electric field strength and electric field intensity?
The electric field strength has direction and hence it is a vector quantity. Intensity means the magnitude or amount. Now field intensity similarly means the magnitude of the strength of the field.
