NEET Physics Resistance & Resistivity Match the Following Question
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 insulators (ii) 10^-8 to 10^-6 Ω m (c) Dependence of resistance on length (iii) Directly proportional (d) Dependence of resistance on area (iv) Inversely proportional
Choose the correct matching:
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-i, d-iii
a-iii, b-ii, c-i, d-iv
Correct Answer
Detailed Explanation
The resistivity of metals typically ranges from 10^-8 to 10^-6 Ω m, while insulators have much higher resistivity, ranging from 10^22 to 10^24 Ω m. Resistance depends on length and cross-sectional area such that it is directly proportional to length and inversely proportional to area.
