Semiconductor – Facts and Physics As I mentioned above, a semiconductor has a dual property – conductor and insulator of electricity. This property depends on impurities added to the semiconductor material (A pure such material is called an “intrinsic”). The impurities added to the material ...
What is the difference between sensible heat and specific heat? Give examples. What is the specific heat of lead? What is pressure in physics? What is tension in science? What is a temperature transducer? Which material is the best thermal insulator?
In physics, a substance that does not easily conduct electricity is called an 'insulator.' Some of the most commonly used insulators are glass, rubber, and plastic. The insulators do not allow the electrons to flow freely from one molecule to another....
Dielectric material is composed of atoms that do not have free-flowing electrons, as the electrons are fixed in place and so cannot conduct electric flow. A dielectric material is able to store electrical energy, which is different from a material that is merely an insulator....
We have already told that semiconductor is useful in electronic circuit elements not only because of its moderate resistivity but because of its many other special properties.Some main properties of semiconductors are, The resistivity is less than an insulator and more than a conductor. The temperatu...
The border line between semiconductors and insulators is rather arbitrary. In particular,the value of the energy gap separating the semiconducting materials from insulating one is not well-defined. For example,diamond(C)was considered for a long time an insulator,but today it is possible to prepa...
A semiconductor has a conductivity between an insulator, like glass, and a conductive metal, such as copper. With a dual nature, semiconductors work as conductors when temperature increases and as insulators with decreasing temperature. Some types of semiconducting materials are made up of a blend ...
When an object is touched with the metal top of an electroscope, its aluminium leaves diverge. What conclusion do you get from this observation ? AThe object is charged BThe object is uncharged CThe objects is an insulator DNone of theseSubmit Which among the following is not a part of ...
By the previous lemma, this is an extremally disconnected CH space. Because every ultrafilter on a CH space has a unique limit, we have a canonical map from to , which one can easily check to be continuous and surjective. Remark 7 In fact, to each CH space one can associate an ...
Electrostatics Physics What is Electrical Capacitance? By admin April 6, 2025 Electrical conductance of a conductor is defined as the capacity to store charge in it. Whenever charge is applied to an insulator its potential is raised to some certain level. Charge on a conductor and its electric ...
