Amara has two different lightbulbs of unknown resistance, a 9V battery, and an ammeter. She wires the bulbs to the battery in series and measures the current through the battery to be 0.2 A, then wires the bulbs to the battery in parallel and measures the current through the battery to be 0.9 A. From these two measurements, determine the resistances of the two bulbs.
