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 (i) all are glowing and (ii) in the situation when two from section A and one from section B are glowing, will be :
(1) 4 : 9
(2) 9 : 4
(3) 1 : 2
(4) 2 : 1
