What kind of material has a high resistivity and prevents the movement of electrons?
An insulator
How do you convert conductivity to resistivity?
Conductivity is a measure of the ability of a substance to conduct electricity. Resistivity is a measure of how strongly a substance resists the flow of an electric current. So conductivity and resistivity are opposed to each other. A good conductor like copper has a low resistivity, and a good insulator like glass has a low conductivity and a high resistivity. Mathematically, conductivity and resistivity are inverses of each other, so it is quite easy to convert conductivity to resistance.
Resistance is affected by a material's?
yes. affected by types of material. conductor is a good material. semiconductor is okay but insulator cannot move the charges through it.
What is temperature coefficient for insulator?
"Temperature coefficient" means, how does a certain physical quantity vary, depending on the temperature. In this case, the physical quantity in question is probably the electrical resistance, or the electrical resistivity.
Difference between semi conductor and semi insulator?
some semiconductors have comparatively low resistivity, and this is due to their containing electrically active impurities with energy-levels near a band edge. Others have very high resistivity and this is due to their containing a predominance of impurities with levels far from the band edges, that is, far compared with the thermal energy kT. These latter materials are often referred to as insulators, but since they can carry electronic currents we prefer to introduce the term 'semi-insulator' to describe them.
What kind of material has a high resistivity and prevents the movement of electrons?
An insulator
How are substances classified on the basis of resistivity?
conductor,semiconductor and insulator
Is uranium a conductor or insulator?
The electrical resistivity of uranium is 28.10-8 ohm.meter; uranium is not an electrical insulator.
Why pure water is considered as insulator?
Yes! Pure distilled water is an insulator. it is the minerals, alkali's and acids in the contaminates that determine the resistivity of water!
What is the resistivity of germanium if they compared to glass?
glass is an insulator, germanium is a metalloid.
Does alumina become conductive at high temperatures?
Alumina is a good electrical insulator; at high temperatures the resistivity is smaller than the resistivity at room temperature.
Is francium an insulator?
Electrical resistivity of francium: 3 μΩ.m.
Is polonium an insulator?
Polonium is not an insulator.The electrical resistivity of polonium is: 0, 40 microohm.meter.
Resistivity range of semiconductors lies between the range of?
Semiconductors have bulk resistivity in the range of 10-4 ohm-cm (heavily doped) to 103 ohm-cm (undoped, or intrinsic).
Is resistivity of a conductor temperature dependent?
A perfect insulator has infinite ohms of resistance.
What would make a good electric insulator?
An electrical insulator is a material whose internal electric charges do not flow freely. Rubber, glass, paper, and Teflon, which have high resistivity, are very good electrical insulators.
