Circuit schematic of four identical bulbs connected to an ideal battery.
A circuit consists of an ideal battery with emf \(\mathcal{E}\) connected to four identical lightbulbs labeled 1, 2, 3, and 4, each with constant resistance \(R\). Bulb 1 is connected in series with the battery and with a parallel network consisting of two branches. One branch contains bulb 2, and the other branch contains bulb 3 and bulb 4 connected in series. Which of the following correctly ranks the brightness (power dissipated) of the four bulbs?
