Physics-Resistance & Resistivity
NEET Physics Resistance & Resistivity Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Resistivity of metals | (i) 10^22 to 10^24 Ω m |
| (b) Resistivity of semiconductors | (ii) 10^–8 to 10^–6 Ω m |
| (c) Resistivity of insulators | (iii) 10^–6 to 10^–4 Ω m |
| (d) Ohm's Law | (iv) R = V/I |
A
a-ii, b-iii, c-i, d-iv
B
a-ii, b-i, c-iii, d-iv
C
a-i, b-iii, c-ii, d-iv
D
a-ii, b-iv, c-i, d-iii
Correct Answer
Option A
Detailed Explanation
The resistivity of metals typically falls within the range of 10^–8 to 10^–6 Ω m, while insulators have a resistivity that can be 10^22 to 10^24 times greater. Ohm's Law is correctly stated as R = V/I.
