Consider four conducting materials copper, tungsten, mercury and aluminium with resistivity ρC, ρT, ρM and ρA respectively(1) ρM > ρA > ρC (2) ρC > ρA > ρT (3) ρA > ρM > ρC (4) ρA > ρT > ρC |

Answer» Answer is (1) ρM > ρA > ρC ρM = 98 × 10–8 ρA = 2.80 × 10–8 ρC = 1.72 × 10–8 ρT = 5.65 × 10–8 ρM > ρT > ρA > ρC |
