What are the advantage of semiconductor over conductor?
semiconductors are the conducors they are partially conduct electricity. And we can increase therir conductivity by using various method . They are Intrinsic method and extrinsic method . Intrinsic method is heating the semiconducter . Extrinsic method is doping. By using this method the conductivity of semiconductors is rapidly increases. Then we use semiconductors are prefferd to conductors
What can be viva question from the transistor characteristics in common emitter?
Transistor Characteristics1) What is transistor? what are the types of transistors?Ans: Transistor is a three terminal semiconductor device.There are two types of semiconductor i.e,. n-p-n and p-n-p.2) Define n-type and p-type semiconductors.Ans: If an intrinsic semiconductoris doped with pentavalent impurity. Then it is called n-type semiconductors.If it is doped with trivalent impurity then it is called p-type semiconductor.3) What is doping?Ans: Adding trivalent or pentavalent impurity to an intrinsic semiconductor is called doping.4. What are three basic transistor connection modes? Which mode is most preferred? Why?Ans: Common-Emitter, Common-Base & Common-Collector connections.CE mode is most preferred because CE modes gives Highest voltage gain.5. Define current amplification factor of a transistor?Ans: It is defined as ratio of change in collector current to change in base current.7. What is the biasing rule of transistor?Ans: Emitter base junction should be forward biased and collector base junction should be reversed biased.8. What is semiconductor?Ans: Semiconductor is a substance which has the resistivity in between that of conductor and insulator. semiconductor has negative temperature coefficient of resistance.9) Which are the commonly used semiconductors?Ans: Germanium & Silicon
What is transistor mos?
Metal Oxide Semiconductor. Usually used when referring to a specific type of transistor which uses this type of semiconductor material: the Field Effect Transistor (FET).
Zener diodes are most commonly used in?
Zener diodes are a form of semiconductor diode that are widely used in electronics circuits as voltage references. Zener diodes provide a stable and defined voltage and as a result Zener diode circuits are often used in power supplies when regulated outputs are needed. Zener diodes are cheap and they are also easy to use and as a result they are used in many applications and many circuits.
What are the applications of digital dice?
its used for playing games
What you understand by the term intrinsic semiconductor and how an intrinsic semiconductor is turned into either a p type or an n type material?
An intransic material is a material that have been used in doping process.There are two type of intrinsic material n type and p type.

When was the semiconductor built?
Semiconductors aren't built, they are chemicals. Maybe you are thinking of semiconductor electronic components. The first semiconductor discovered was galena (lead sulfide) which was first used in a practical electronic component in 1874. The next semiconductor discovered was copper oxide which was first used in a practical electronic component in 1924. After that many others were discovered including selenium, germanium, and silicon. It was not practical to build electronic components using silicon until 1958 when Fairchild perfected their silicon mesa process, then in 1959 their silicon planar process.
