2. A battery with no internal resistance is connected to five identical light bulbs, A, B, C, D and E, as shown in the figure. The potential difference between the terminals of the battery is Vand the resistance of each bulb is R. a) What is the current through the bulb C in terms of Vand R? b) Rank the bulbs in order of brightness from brightest to dimmest. If two bulbs are the same brightness, state that explicitly. c) Suppose that bulb D is burned out: that is, its filament breaks and current can no longer flow through it. What happens to brightness of the bulb B and bulb E?
