Question

In 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

Answer: (A)

Copper<Nichrome<Germanium<Silicon

Answer 2

Materials	Resistivity , ij
Copper (Cu)	$1.7 \times 10 ^ { - 8 }$
Nichrome (alloy of Ni, Fe, Cr),	$100 \times 10 ^ { - 8 }$
Germanium	$0.46$
Silicon	2300

Hence, the option (1) is correct
