Q62
If a small amount of Cu is added to a Ni conductor, then the
A.
resistivity of Ni will increase at all temperatures because Cu is a better conductor than Ni
B.
residual resistivity of Ni at low temperature will increase as Cu atoms act as defect centres
C.
resistivity of Ni will increase at all temperatures as Cu destroys the periodicity of Ni and acts as defects
AnswerD.
resistivity of Ni remains unaltered as Cu atoms give the same number of free electrons as Ni atoms
