NEET Physics Resistance & Resistivity Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Insulators | (i) Low resistivity |
| (b) Metals | (ii) High resistivity |
| (c) Semiconductors | (iii) Resistivity decreases with temperature |
| (d) Conductors | (iv) Resistivity remains constant with temperature |
a-ii, b-i, c-iii, d-iv
a-ii, b-iv, c-iii, d-i
a-i, b-ii, c-iv, d-iii
a-iv, b-i, c-iii, d-ii
Correct Answer
Detailed Explanation
Insulators have high resistivity (greater than 10^18 ohm-m), while metals have low resistivity (ranging from 10^-8 to 10^-6 ohm-m). Semiconductors exhibit a decrease in resistivity with increasing temperature, and conductors generally maintain a resistivity that does not significantly change with temperature.
