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) Ohm's Law | (i) V = IR |
| (b) EMF of a cell | (ii) e = V + + V – |
| (c) Resistance | (iii) ρ = RA/L |
| (d) Resistivity | (iv) R = ρL/A |
A
a-i, b-ii, c-iv, d-iii
B
a-ii, b-i, c-iv, d-iii
C
a-i, b-iii, c-ii, d-iv
D
a-iv, b-ii, c-iii, d-i
Correct Answer
Option A
Detailed Explanation
Ohm's Law is correctly matched with its formula, V = IR. The EMF of a cell is defined as e = V + + V –. Resistance is represented as R = ρL/A, while resistivity is defined by the formula ρ = RA/L.
