Six similar bulbs are connected as shown in the figure with a DC source of emf $E$, and zero internal resistance.
The ratio of power consumption by the bulbs when $\left(\mathrm{i}\right)$ all are glowing and $\left(\mathrm{ii}\right)$ in the situation when two from section $A$ and one from section $B$ are glowing will be,
