Arrange the following in the order of increasing resistivity (ρ) (A)…

The correct answer is Option (1) → (B), (A), (D), (E), (C)

Metals have the lowest resistivity, semiconductors lie in between, and insulators have the highest. Graphite, though a conductor, has a resistivity far above that of metals. Typical values at room temperature are:

    \( (B)\ \text{Silver}: 1.6\times10^{-8}\,\Omega\,\mathrm{m} \)
    \( (A)\ \text{Copper}: 1.7\times10^{-8}\,\Omega\,\mathrm{m} \)
    \( (D)\ \text{Carbon (graphite)}: 3.5\times10^{-5}\,\Omega\,\mathrm{m} \)
    \( (E)\ \text{Germanium}: 0.46\,\Omega\,\mathrm{m} \)
    \( (C)\ \text{Glass}: 10^{10} \text{ to } 10^{14}\,\Omega\,\mathrm{m} \)

So the order of increasing resistivity is B, A, D, E, C.

Note: This question is from the pre-rationalised NCERT book (2022-23). The topic was removed from the latest NCERT book (2026-27), but it is still in the CUET 2026 syllabus, so do not skip it.
