What are the properties of Conducting Materials with respect to temper

1.	What are the properties of Conducting Materials with respect to temperature coefficient of resistance and tensile strength?(a) low temperature coefficient, low tensile strength(b) low temperature coefficient, high tensile strength(c) high temperature coefficient, low tensile strength(d) high temperature coefficient, high tensile strengthThis question was posed to me during an interview.I'm obligated to ask this question of Electrical Conducting Materials in portion Electrical Engineering Materials of Design of Electrical Machines
Answer» Correct choice is (b) low TEMPERATURE coefficient, high tensile strength The EXPLANATION is: The resistance of the material should not increase with temperature rise. This can LEAD to the loss of conduction property. High tensile strength allows in withstanding external disturbances, for SMOOTH functioning.
