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
Choose the correct matching:
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.
