Know the Answer?

Digger · Answer 1

Metal alloys, for example, Ag-Cd that have very low temperature coefficient of resisitance.

Sean Forbes · Answer 2

Resistance of semi conductors such as germanium, selenium, silicon decreases with temperature because more covalent bonds in semiconductor get broken with rise of temperature providing more number of electrons and holes as current carriers
