Materials and Components If a small amount of Cu is added to Ni conductor, then Resistivity of Ni will increase at all temperatures as Cu destroys the periodicity of Ni and acts as defects Residual resistivity of Ni at low temperature will increase as Cu atoms act as defect centres Resistivity of Ni will decrease at all temperatures because Cu is a better conductor than Ni Resistivity of Ni remains the same Resistivity of Ni will increase at all temperatures as Cu destroys the periodicity of Ni and acts as defects Residual resistivity of Ni at low temperature will increase as Cu atoms act as defect centres Resistivity of Ni will decrease at all temperatures because Cu is a better conductor than Ni Resistivity of Ni remains the same ANSWER DOWNLOAD EXAMIANS APP

Materials and Components An atom of a rare gas is placed is an electric field E. Then The nucleus will be shifted in a direction opposite to that of E. The nucleus will not be shifted. The nucleus will be shifted in the direction of E by an amount which is proportional to E. The nucleus will be shifted in the direction of E by an amount which is independent of E. The nucleus will be shifted in a direction opposite to that of E. The nucleus will not be shifted. The nucleus will be shifted in the direction of E by an amount which is proportional to E. The nucleus will be shifted in the direction of E by an amount which is independent of E. ANSWER DOWNLOAD EXAMIANS APP
