AIPMT PRELIMS 2000 Physics Resistance MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Two bulbs of (40 W, 200 V), and (100 W, 200 V). Then correct relation for their resistance :
A
R₄₀ < R₁₀₀
B
R₄₀ > R₁₀₀
C
R₄₀ = R₁₀₀
D
No relation can be predicted
Correct Answer
Option B
Detailed Explanation
Resistance is inversely proportional to power for the same voltage. Thus, R₄₀ > R₁₀₀.
