Options

  1. A2 Ω
  2. B9 Ω
  3. C18 Ω
  4. D5 Ω

Correct answer

D. 5 Ω

Step-by-step solution

Equivalent circuit i 1 : i 2 : i 3 = 1 2 : 1 6 : 1 3 = 3 : 1 : 2 i 1 = 3 6 × i = i 2 i 2 = 1 6 × i = i 6 i 3 = 2 6 × i = i 3 Δ H in 5 Ω = i 2 × 5 ∆ H in 2 Ω = i 2 4 × 2 = i 2 2 ∆ H in 9 Ω = 4 i 2 9 × 9 Maximum heat is in 5 Ω .
