NEET Chemistry Conductance MCQ Question
If the electrical resistance of an electrolytic solution is 4 ohms and the length and area of cross-section are 2 m and 0.5 m² respectively, what is the resistivity of the solution?
1 ohm m
2 ohm m
4 ohm m
8 ohm m
Correct Answer
Detailed Explanation
Using the formula R = ρ(l/A), where R = 4 ohms, l = 2 m, and A = 0.5 m², we calculate resistivity ρ = R * (A/l) = 4 * (0.5/2) = 1 ohm m.
