What is doping process?
It is the addition of impurities to a semi-conductor in order improve their electrical conductivity.
What will happen when doped semiconductor is heated will its conductivity increase or decrease?
Doping a semiconductor means to introduce impurities to the semiconductor in order to alter it. For the most part, doping a semiconductor increases its conductivity.
Which electrical device must have high resistance in order to function properly?
voltmeter
What is the house earthing?
The term 'house earthing' is used in the electrical wiring of a structure in order to ground the house against electrical leakage which can cause increased power usage and the possibilty of safety concerns involving electrical shock.
Which metal is used for electrical contacts?
Copper is used the majority of the time. Gold is sometimes because it does not corrode. Tungsten is used in light bulbs because it is a good resistor and resists the flow of electrons. Aluminum and silver are also sometimes used. There is also some recent research in safely using sodium and lithium.
The electrical conductivity of metals which is expressed in ohm 1 m 1 is of the order of?
10^6
What is doping process?
It is the addition of impurities to a semi-conductor in order improve their electrical conductivity.
Which metal has the highest conductivity?
At room temperature, silver has the highest electrical and thermal conductivity of all the (known) metals. Note that diamond, an allotrope of carbon, is a poor electrical conductor but is several times better as a thermal conductor than silver. Carbon is a nonmetal, of course, but it was worth mentioning as both a comparison and a curiousity.
Silver is the best electrical conductor but why do some people say Platinum is?
Because they don't know any better. (Plantinum's conductivity is 9,661,000 /ohm.m , Silver's is 63,010,000 /ohm.m ) This would actually be expressed in Siemens. Ohm is a measure of resistance not conductivity. The numbers may be correct however. I haven't done the math. The most conductive of all metals are silver, copper and gold in that order. Silver is also the most thermally conductive element, and the most light reflecting element. Silver also has the unusual property that the tarnish that forms on silver is still highly electrically conductive. Platinum has a much higher melting point than silver and gold ...etc so in some applications, while it is not as good of a conductor, it is the only one that can be used.
What is the old name for Siemens the unit for electrical conductivity?
Old units for electrical conductivity (EC)SI units of electric resistance and electric conductance are ohm (Ω) and siemens (Si). The unit mho ("ohm" in reverse order) for conductance should no longer be used (1 mho = 1 Si). abohm and abmho are older units from the centimetre-gram-second electromagnetic system. statohm and statmho are from the centimetre-gram-second electrostatic system.see also this forum http://landviser.us/phpBB3/viewtopic.php?f=4&t=3&p=19#p19The question is about conductivity, not, as the above answer, conductance. The siemens in the unit of measurement for conductance, whereas the siemens per metre is the unit for conductivity.
What will happen when doped semiconductor is heated will its conductivity increase or decrease?
Doping a semiconductor means to introduce impurities to the semiconductor in order to alter it. For the most part, doping a semiconductor increases its conductivity.
