Question

Arrange the following materials in increasing order of their resistivity,
Nichrome, Copper, Germanium,Silicon
A. `"Copper" lt "Nichrome" lt "Germanium" lt "Silicon"`
B. `"Germanium" lt "Copper"lt "Nichrome" lt "Silicon"`
C. `"Nichrome" lt "Copper" lt "Germanium" lt "Silicon"`
D. `"Silicon" lt "Nichrome" lt "Germanium" lt "Copper"`

Answer 1

Correct Answer - A
`{:("Materials","Resistivity" (rho)(Omega "m at 0"^(@)C)),("Copper (Cu)",1.7 xx 10^(-8)),("Nichrome",100 xx 10^(-8)),("(alloy of Ni, Fe, Cr)",),("Germanium",0.46),("Silicon",2300):}`
