Materials and Components For making a capacitor it is better to have a dielectric having Permittivity which is neither high nor low High permittivity Permittivity same as that of air Low permittivity Permittivity which is neither high nor low High permittivity Permittivity same as that of air Low permittivity ANSWER DOWNLOAD EXAMIANS APP
Materials and Components If a small amount of Cu is added to Ni conductor, then Resistivity of Ni remains the same 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 will increase at all temperatures as Cu destroys the periodicity of Ni and acts as defects Resistivity of Ni remains the same 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 will increase at all temperatures as Cu destroys the periodicity of Ni and acts as defects ANSWER DOWNLOAD EXAMIANS APP
