NEET Physics Resistance & Resistivity Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Resistivity of metals | (i) Increases with temperature |
| (b) Resistivity of insulators | (ii) Very low values |
| (c) Conductivity of materials | (iii) High values |
| (d) Temperature effect on resistivity | (iv) Decreases with temperature |
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-i, c-iii, d-iv
a-iii, b-ii, c-i, d-iv
Correct Answer
Detailed Explanation
Metals have low resistivities (10^-8 to 10^-6 Wm) and their resistivity generally increases with temperature, while insulators have high resistivities (10^18 times greater than metals). Conductivity is inversely related to resistivity.
