The circuit diagrams depict two lamps X and Y, each connected to a cell. For lamp X, the current is $0.50\,\text{A}$ and the resistance is $9.6\,\Omega$. For lamp Y, the current is $3.0\,\text{A}$ and the resistance is $1.2\,\Omega$. Find the ratio $\dfrac{\text{power in lamp X}}{\text{power in lamp Y}}$?
