All capacitors used in the diagram are identical and each is of capacitance C. Then the effective capacitance between the point A and B is

Options

  1. A1.5 C
  2. B6 C
  3. CC
  4. D3C

Correct answer

A. 1.5 C

Step-by-step solution

The equivalent diagram of the given circuit is C ₁, C ₂ and C ₃ are in parallel aligned C ₁₂₃ &= C ₁+ C ₂+ C ₃ &= C + C + C =3 C aligned Similarly, C₄₅₆=3 C C ₁₂₃ and C ₄₅₆ are in series C_ eq = (3 C)(3 C) 3 C+3 C =1.5 C
