Arrange the following in the order of increasing resistivity (ρ)
(A) Copper
(B) Silver
(C) Glass
(D) Carbon (graphite)
(E) Germanium
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (B), (A), (D), (E), (C)
Typical resistivities (ρ) in Ω·m:
Silver: $1.6 \times 10^{-8}$
Copper: $1.7 \times 10^{-8}$
Germanium: $0.46$
Carbon (graphite): $3 \times 10^{-5}$
Glass: $10^{10}$
Increasing order of resistivity:
Silver < Copper < Carbon (graphite) < Germanium < Glass
