Polarization per unit applied electric field is given by
The correct answer is: electric susceptibility
Two parallel plates have equal and opposite charges. When the space between them is evacuated the electric intensity is 3 × 105V/m and when the space is filled with dielectric the electric intensity is 1.0 × 105V/m. The induced charge density on the surface of the dielectric.
Electrified in vacuum
Surface density of induced charges,
The correct answer is:
Polarization in a dielectric on application of electric field is
The correct answer is: Displacement / separation of opposite charge centers
The outer sphere of spherical capacitor is earthed. For increasing its capacitance.
The correct answer is: dielectric material is filled between the two spheres
The relation between bound charge density ρb to free charge (extraneous charge) ρf is given by
The correct answer is:
If is the polarization vector and
is the unit vector normal to the surface then a polarized piece of a dielectric can be regarded as equivalent to
The correct answer is: charges of a volume density and surface charges of density ρb is given by
The susceptibility of a polar dielectric is temperature dependent because
The correct answer is: They are necessarily anisotropic in a nature
At the boundary or interface between two dielectric media the vector and
are such that
The correct answer is: The tangential component of and the normal component of
is same on each side of the boundary. The latter condition is however, valid only in the absence of any free charges on the interface
In a dielectric conductor boundary (interface). The tangential component of electric field is
The correct answer is: 0
The behavior of a dielectric is
The correct answer is: different for static and varying field and is very much depend on the frequency
