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.
Can the batteries used in the torch lights be recharged after their discharge? Give reason? Ans) No,because the NH4Cl corrods the zn containger gradually.so with out anode redox
