The electrical resistance of a mercury column in a cylindrical container is `R` the mercury is poured into another cylindrical container with half the

D) a, b, c and d

Correct option is C) 4 Ω

Column I Column II 1. G: Phase (b) 2-5 Hours 2. Gi Phase (d) 8 Hours 3. M Phase (a) 1-3 Hours 4. S Phase (c) 6-8 Hours

Column I Column II 1. Lightening b. 10000 A 2. House hold circuits a. Few amperes

Given: R0 = 2.5 Ω α = 4 × 10-3/°C = 0.004/°C T = 80 °C To find: Resistance at 80 °C (RT) Formula: RT = R0(l + αT) Calculation: From formula, RT = 2.5 [1+ (0.004 × 80)] =...
