O K is absolute zero. At absolute zero, the electrons of the semi conductors are trapped and are immovable from their electron shell as they are in a low energy state. This makes the pure semiconductor an insulator. One must heat the semiconductor to give the electrons enough energy to move to free them from their electron shell, and thus conduct.

The circuit is incomplete, you will have no continuity, no flow of current to the load or other components. The voltage across every component in the circuit is zero. No part of the circuit stores or dissipates any energy. In short, the circuit doesn't work.
absolute zero is the essence of nothing and nothing is a quantity of zero.
its nothing but alternate occurence of pole/zero and zero/pole. ex: f(s)=s*(s+2)/(s+1). here we can easily sense that there is a occurence of zero(s=0),pole(s=-1),zero(s=-2).
frequency if it will not zero then we cant tell its dc ...AnswerFrequency is the number of alternations per unit time. As d.c. doesn't alternate, then zero divided by any quantity of time is zero!
At absolute zero (0K), an intrinsic semiconductor will act like a perfect insulator. At this temperature, the electrons in the valence band will remain there. The heat energy required to excite the electrons from the valence band to the conduction band is insufficient at 0K. When the temperature increases, some of the electrons from the valence band got excited and moves to the conduction band. This will give rise to the conductivity of the semiconductor. i.e in 0 k(0 kelvin) the pure semi conductor the electrons in the valance band don't do any thing.They are lazy for conductivity.But when increasing the temperature increase the energy of electrons and they try to move.At the end electrons win and they can to move.So it happened a conductivity.
Yes, it is. More specifically it is zero-band-gap semiconductor http://plaza.ufl.edu/tongay/

dormant semiconductor
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
Porcelain is an insulator, its resistance approximates infinity.
Pottery is an insulator. Both electrical and thermal. However earthenware (low fired clays like brick) can be porous (liquids can penetrate it) and if the liquid is an electolyte (like salt water), certain electrical conduction can take place.
In low voltage and electronics Leakage Current is any current that flows when the ideal current is zero. In medium and high voltage applications it is the current that flows either through the body or over the surface of an insulator. Leakage current often arises when outdoor insulation is submitted to conductive fog (sea mist/spray, industrial smogs) or when a pollution layer containing soluble salts is formed on the insulator surface and then wetted, for example by dew or mist. These currents can reach several hundred mA and may lead to flashover of the insulation.
At absolute zero they don't move.The more you cool, the less Brownian motion of particles!
Sub-Zero looks like this:. Happy? :) :) :) :) :) (: (: (: (: (: (:
Because it is 0
Yes, it contains lots of ionised salts that allow current to flow. Its a conductor. Not a good conductor, but it conducts.
