Is electric flux density scalar or vector?
Scalar
Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
Where is an electric field the strongest?
Near the poles, weakest at the midpoint between them
Gets stronger as you get closer to an electric charge?
The electric field gets stronger as you get closer to an electric charge.
How is the strength of an electric field indicated with electric field lines?
Given a positive charge the electric field lines are drawn starting from the charge and pointing radially outward, ending in principle at infinity, according to the electric field strength being proportional to the inverse square of distance. From the definition of electric field we know that the modulous of the electric field is greater for smaller distances from the field generating charge. Since the electric field lines point radially outward we consider the density of lines an indication of the strength of the electirc field. If we immagine to trace a circle around the electric field generating charge, of radius slightly greater than the radius of the object which holds the charge and therefore generates the electric field, such circle will be crossed by a number 'n' of lines. The density of lines crossing the cirle will then be the circumference of the circle divided by the number 'n' of lines. For a larger circle we will have a greater circumference, but same number of lines 'n', and therefore a smaller density of lines crossing it, which idicates a lower intesity of electric field for a greater distance from the charge.
What is the significance of electric dipole in a polar molecule when an external electric field is applied?
in magnetic relays
What is flux density related to?
In case of electrostatics, flux density = electric field intensity and in case of magnetism, flux density = magnetic field induction
What are the difference between elactric field and electric displacement field?
The electric displacement field is a vector field, shown as D in equations and is equivalent to flux density. The electric field is shown as E in physics equations.
What is the Difference between line charge density and surface charge density?
The electric field of an infinite line charge with a uniform linear charge density can be obtained by a using Gauss' law. Considering a Gaussian surface in the form of a cylinder at radius r, the electric field has the same magnitude at every point of the cylinder and is directed outward. The electric flux is then just the electric field times the area of the cylinder.
How does the electric field between the capacitors change with their separation?
Electric field is got by the expression = charge density / epsilon not As so long charges on the plate remain the same the electric field also remains the same
Is electric flux density scalar or vector?
Scalar
What is the conductivity of electricity?
conductivity is the ratio of current density to the electric field
What are the physical significance of Maxwell's equations?
As per my knowledge,Maxwell's equations describes the relations between changing electric and magnetic fields. That means time varying electric field can be produced by time varying magnetic field and time varying magnetic field can be produced by time varying electric field.
What is The significance Of the magnetic quantum number?
magnetic quantum number tells about the orientation of atomic orbitals which is actually obtained as a resolution due to the application of magnetic or electric field (stark effect).It is very significant and it has many applications
What is field density test?
field density test

The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
