From: JEE Main 2020 (Online) 2nd September Morning Slot
Question
Consider four conducting materials copper,
tungsten, mercury and aluminium with
resistivity C, T, M and A respectively. Then :
Choose an option
Show full solutionCorrect option: B
Correct answer
BM > A > C
Step-by-step explanation
ρM = 98 × 10–8
ρA = 2.80 × 10–8
ρC = 1.72 × 10–8
ρT = 5.65 × 10–8
M > T > A > C
ρA = 2.80 × 10–8
ρC = 1.72 × 10–8
ρT = 5.65 × 10–8
M > T > A > C
