Question # 1

Define Saturation and Remanence of Hysteresis Loop.

Ans 1: Saturation: The material is said is reduced to magnetically saturated when magnetic flux density reaches a maximum value.
Remanence: When the current is reduced to zero,the material still remains strongly magnetize.It is due to the tendency of domains to stay partly in line,once they have been aligned,It is called remanence or relativity.

Question # 2

Differentiate between ductile and brittle substance,Give their examples.

Ans 1: Ductile substance:Substance that undergo plastic deformation unit they break are called ductile substance.Lead copper,and wrought iron are ductile.
Brittle substance: The substance which break just after the elastic limit reached are known as brittle substance.Glass and high carbon steel are brittle.

Question # 3

Distinguished between a valence and a conduction band.

Ans 1: Valence bond: The energy band occupied by valence electrons is called the valence band.
Ans 2: Conduction band:The energy band are occupied by free electrons is called the conduction band.

Question # 4

How the conductivity of semiconductor can be raised?

Ans 1: The conductivity of a semiconductor can be raised by the process of doping in which small number of impurity atoms are added to pure semiconductors.

Question # 5

What is the difference between intrinsic and extrinsic semiconductors?

Ans 1: Intrinsic Semiconductor:A semiconductor in its extremely pure form is known as Intrinsicsemiconductors,Pure elements of silicon and germanium are Intrinsic semiconductors,These semiconductors elements have atoms with four valence electrons.
Ans 2: Extrinsic Semiconductor: The doped semiconductors material are called Extrinsic Semiconductor.The electrical behaviour of semiconductors is substantially changed introducing a small impurity into pure semiconductors,and this process is called doping.

Question # 6

What is meant by strain energy?How can it be determined from the force extension of graph?

Ans 1: The amount of P.E stored in a material due to displacement of its molecule from its equilibrium position.under the action of stress is called strain energy,Strain energy can be determined from the force extension graph according to the following reasons
Strain energy=1/2L₁F₁

Question # 7

Define stress and strain,What are their units.

Ans 1: The force applied on unit area to produce any change in the shape,volume or length of the body is called stress,its SI units is pascal.
And strain is the measure of deformation of solid when stress is applied to it.It has no unit.

Question # 8

Define UTS of a material.

Ans 1: The maximum stress that a material can withstand is called ultimate tensile stress.

Question # 9

Define stress and write its formula.

Ans 1: It is defined as the force applied on unit are to produce any change in shape,volume or length of a body.Its formula is
Stress=Force/Area

Question # 10

Distinguished between p-type semiconductor and n-type semiconductor.

Ans 1: p-type semiconductor:When a trivalent impurity such as aluminium is added into the semiconductor,holes are generated and p type semiconductor is formed.Holes are positive charge carrier.
Ans 2: n-type semiconductor: When a pentavalent impurity such as phosphorus is added into the semiconductor,free electrons are generated and n type semiconductor is formed.Charge carriers is in n-type are free electrons.
