Question # 1

Define elastic limit and Yield point.

  • Ans 1: The greatest stress that a material can endure without any permanent deformation is called elastic limit.This kind of behavior is called elasticity.
    Yield point: The point on the stress-strain curve beyond which if stress is further increased then permanent deformation takes place in the given specimen.This is called yield point.

Question # 1

How n type semiconductors are formed?

  • Ans 1: When a silicon crystal is doped with a pentavalent element,e.g arsenic,antimony or phosphorus etc.four valence electrons of the impurity atom form covalent bond with the four neighbouring Si atoms,while the fifth valence electrons provide a free electron in the crystal.Such a doped semiconductor is called n type semiconductor.
