The value of current in the 6 Ω resistance is:

Options

  1. A4   A
  2. B8   A
  3. C10   A
  4. D6   A

Correct answer

C. 10   A

Step-by-step solution

Applying K C L at point P , V - 0 6 + V - 90 5 + V - 140 20 = 0 ⇒ 10   V + 12   V - 1080 + 3   V - 420 = 0 ⇒ V = 60 ∴ Current in 6   Ω = V - 0 6 = 10   A Hence, option 3 .
