Three capacitors each of 4 μ F are to be connected in such a way that the effective capacitance is 6 μ F . This can be done by connecting them

Options

  1. Aall in series
  2. Ball in parallel
  3. Ctwo in parallel and one in series
  4. Dtwo in series and one in parallel

Correct answer

D. two in series and one in parallel

Step-by-step solution

For top branch, 1 C eq = 1 4 + 1 4 ⇒ C eq = 2   μF For parallel combination, C net = 2 + 4 = 6   μF
