When a small amount of Cu is added to a Ni conductor, then the?a) Resistivity of Ni will decrease at all temperatures because Cu is better conductor than Nib) Residual resistivity of Ni at low temperatures will increase as Cu atoms acts as defect centersc) Resistivity of Ni will increase at all temperatures as Cu destroys the periodicity of Ni and acts as defectsd) Resistivity of Ni remains unaltered...
