Physics-Resistance & Resistivity
NEET Physics Resistance & Resistivity Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
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
Choose the correct matching:
A
a-ii, b-iii, c-i, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-ii, b-i, c-iii, d-iv
D
a-iii, b-ii, c-i, d-iv
Correct Answer
Option A
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.
