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. Silicon $<$ Nichrome $<$ Germanium $<$ Copper

Answer 1

The correct option is A Copper $<$ Nichrome $<$ Germanium $<$ Silicon

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