WebDec 27, 2024 · The brightness of a lightbulb is given by its power. P = I2R, and so brightness depends on current and resistance. If the bulbs are identical, they have the same resistance. Therefore, when you are asked to rank the brightness of identical bulbs, you are really being asked to rank the amount of current through each. WebBulb C is the brightest because the voltage across it equals that of the battery. Bulbs A and B share the voltage of the parallel branch of the circuit and have half the current of bulb C (assuming resistances are independent of voltages). If bulb A is unscrewed, the top branch is no longer part of the circuit and current ceases in both A and B.
