1 microfarad is equal to:
The microfarad (symbolized µF) is a unit of capacitance, equivalent to 0.000001 (10 to the -6th power) farad.
The polarized dielectric is equivalent to ________
A polarized dielectric is equivalent to two charged surfaces with induced charges (polarization charges).
The dielectric constant of a metal is:
The dielectric constant of metal is infinite as the net electric field inside the metal is zero.
Which of the following statements is not true for polar molecules?
The extent of polarization depends on
The extent of polarization of dielectrics depends on the relative strength of two mutually opposite factors - the dipole potential energy tending to align the dipole with the external field and thermal energy tending to disrupt the alignment.
A uniformly polarized dielectric amounts to induced ______ charge density but no ______charge density.
As charges are separated on the surface of the dielectric but not in its interior volume.
When a conductor is placed in an electric field; its free charge carriers adjust itself in order to oppose the electric field. This happen until
The dipole moment per unit volume is called:
The electric dipole moment per unit volume is called polarization or polarization density (vector p). It is always directed from negative charge to positive charge.
The displacement of charges inside the dielectric stops when
The displacement of charges inside the dielectric stops when the external force on the charges of the molecules is balanced by the force due to internal fields.
The electric field inside a dielectric decreases, when it is placed in an external electric field. This happens due to ________
The external electric field polarizes the dielectric and an electric field is produced.
The net electric field inside the dielectric decreases due to polarization.
