Combination of Resistors – Power Dissipation

Start Practice →

  1. 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: [add image]
    A $4:9$
    B $9:4$
    C $1:2$
    D $2:1$
