The capacitance between the points A and B in the following figure.

Options

  1. A3 8 F
  2. B9 4 F
  3. C4 5 F
  4. D2 F

Correct answer

B. 9 4 F

Step-by-step solution

The given circuit diagram can be represented as Since, C₁ C₂ = C₃ C₄ = 1 3 Hence, given circuit follows the condition of balance wheatstone bridge. Hence, capacitor C₅ is ineffective. Now, the circuit diagram is redrawn as C_ A B = C₁ C₂ C₁+C₂ + C₃ C₄ C₃+C₄ = 1 3 1+3 + 2 6 2+6 = 3 4 + 12 8 = 9 4 F
