Explain the term- Zener Breakdown
Under a very high reverse voltage, depletion region expands and potential barrier increases resulting in a very high electric field (3X107 V/m) across the junction. Electric field would break some of the covalent bonds of semiconductor reverse current. This is known as Zener effect. Breakdown occurs at a particular and constant value of reverse voltage known as the breakdown voltage.
(UNIFORM VELOCITY) (i) When instantaneous velocity and average velocity of a body are equivalent, then the body moves with uniform velocity. (ii When instantaneous velocity
It is the ratio of the internal electric field induced by the charges on the surface on the dielectric when an external field applied to the polarization of the dielectric.
It is found that when a liquid is free from the external forces, it always gets the shape of a spherical drop. It is due to, for a needed mass, a sphere has the least field area. I
