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.
Regard as three resistors having three unique values of resistance. Presume the resistors are connected in series with each other. Additional suppose that the series combination of
The current in a coil changes of 5A to 10A in 10 -2 s. Then an emf of 50 mill volts is induced in a coil neat it. Determine the mutual inductance of the coil.
Coulomb; C (after C. de Coulomb, 1736-1806) The derived SI unit of electric charge, described as the amount of charge transferred through a current of 1 A within a period of 1
