If a small amount of Cu is added to Ni conductor, then
A.
resistivity of Ni will decrease 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
|
D.
resistivity of Ni remains the same
|
