MATERIALS AND COMPONENTS QUIZ

Decrease in metals as well as in intrinsic semiconductor

Increase in metals but decrease in intrinsic semiconductor

Decrease in metals but increase in intrinsic semiconductor

Increase in metals as well as in intrinsic semiconductor

False

True

The material may become an insulator

The superconducting property may be affected and resistivity may increase from zero to a low value

The superconducting property may be destroyed

The superconducting property is not affected

Resistivity of Ni will increase at all temperatures as Cu destroys the periodicity of Ni and acts as defects

Resistivity of Ni remains the same

Resistivity of Ni will decrease at all temperatures because Cu is a better conductor than Ni

Residual resistivity of Ni at low temperature will increase as Cu atoms act as defect centres

True

False
