Question

Arrange the following materials in increasing order of their resistivity,
Nichrome, Copper, Germanium, Silicon

• A. Copper $<$ Nichrome $<$ Germanium $<$ Silicon
• B. Germanium $<$ Copper $<$ Nichrome $<$ Silicon
• C. Nichrome $<$ Copper $<$ Germanium $<$ Silicon
• D. Nichrome $<$ Germanium $<$ Copper $<$ Silicon

Answer 1

Answer: (A)

Materials$\quad$	Resistivity $\left(\rho\right)\,$ ($\Omega\,m$ at $0^{\circ}C$)
Copper $(Cu)$$\,\,$	$1.7 \times 10^{-8}$
Nichrom (alloy of $Ni$, $Fe$, $Cr$)$\,\,$	$100 \times 10^{-8}$
Germanium$\,\,$	$0.46$
Silicon$\,\,$	$2300$
