As illustrated, a battery is connected to three resistors with resistances $12\,\Omega$, $6\,\Omega$ and $2\,\Omega$. The current supplied by the battery is $3\,\text{A}$. What is the value of the ratio $\dfrac{\text{power dissipated in the resistor of resistance } 6\,\Omega}{\text{power dissipated in the resistor of resistance } 2\,\Omega}$?
- A$\dfrac{1}{3}$
- B$\dfrac{4}{3}$
- C$\dfrac{2}{1}$
- D$\dfrac{3}{1}$
