Reaction Paper On Dielectric Strength

Dielectric strength is the maximum voltage which the dielectric material can withstand before its breakdown. The dielectric strength of the substance is measured through the thickness or width of the dielectric material and is measured in terms of volts per meter.

Dielectric Relaxation

The effect on the dipole moment when the when the dielectric substance is removed form electric field after a long time application of the electric field so that the dielectric substance is fully polarized. When the dielectric substance is place in the Electric Filed the material gets polarized so that their electric field of all the dipoles will be in the same direction now if we remove the electric field then the arrangement of the molecules, their electric field direction, and the dipole moment of the molecules starts changing because of the collision and the random motion of the molecules and this disorientation occurs exponentially which depend on the properties of the material Dipolar polarization fails to follow the external electric field frequency starting for the micro wave frequencies (〖10〗^11). Ionic polarization fails to compete the external electric field frequency form far

In Dielectric materials these band are separated by a large energy gap and all the electrons resides in the valence band. When the electron is given the energy equal to its band gap then the electron will conduct electricity. A strong electric field is capable of providing so much energy that the electrons in the dielectric substance are shifted to then valence band once the electron get in the conduction band it conducts electricity and we can say that a break down has occurred in the insulating dielectric material because now it is conducting
