Electrical and thermal properties Flashcards
1
Q
What is the affect of plastic deformation on electrical conductivity?
A
Plastic deformation reduces conductivity due to more dislocations in the structure.
2
Q
Under what conditions is a material classed as a super conductor, and at what temperature?
A
Metal with zero resistivity. Critical temperature.
3
Q
What range of resistivity are semi conductors?
A
x10^10 to x10^-4 ohms.
4
Q
What range of resistivity are insulators and dielectrics?
A
Resistivity above 10^10 ohms. E.g ceramics, glasses and polymers.
