Three capacitors each of capacity $4 \mu \mathrm{F}$ are to be connected in such a way that the effective capacitance is $6 \mu \mathrm{F}$. This can be done by:
  1. connecting all of them in series
  2. connecting them in parallel
  3. connecting two in series and one in parallel
  4. connecting two in parallel and one in series

Solution

$\begin{aligned} & \mathrm{C}_{\mathrm{AB}}=(2+4) \mu \mathrm{F} \\ & =6 \mu \mathrm{F} \end{aligned}$
