Question

Consider four conducing materials copper, tungsten, mercury and aluminum with resistivity ρ C , ρ T , ρ M and ρ A respectively. Then :, ρ C > ρ A > ρ T, ρ M > ρ A > ρ C, ρ A > ρ T > ρ C, ρ A > ρ M > ρ C

MARKS App · Accepted Answer

ρ M = 98 × 10 - 8 Ω m ρ A = 2 . 65 × 10 - 8 Ω m ρ C = 1 . 724 × 10 - 8 Ω m ρ T = 5 . 65 × 10 - 8 Ω m
