NEET Physics Resistance & Resistivity Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Resistivity of a material | (i) Inversely proportional to the number of free electrons |
| (b) Internal resistance of a cell | (ii) Depends on temperature |
| (c) Power loss in transmission lines | (iii) Inversely proportional to voltage squared |
| (d) Equivalent EMF in series | (iv) Sum of individual EMFs |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The resistivity of a material is affected by the number of free electrons and their average collision time, as noted in the context. The internal resistance of a cell does depend on factors like its design and temperature, while power loss in transmission lines is inversely proportional to the square of the voltage. The equivalent EMF in a series is indeed the sum of individual EMFs.
