Two capacitors $C_1 = 2 \,\mu F$ and $C_2 = 6 \,\mu F$ are connected in series. This combination is then connected in parallel with a third capacitor $C_3 = 4 \,\mu F$. This entire arrangement is connected to a battery of $2 \,V$. What is the energy supplied by the battery to charge the capacitors?

  • A
    $22 \times 10^{-6} \,J$
  • B
    $11 \times 10^{-6} \,J$
  • C
    $\left( \frac{32}{3} \right) \times 10^{-6} \,J$
  • D
    $\left( \frac{16}{3} \right) \times 10^{-6} \,J$
