Is a light bulb a resistor? - Answers

WebThen, realizing that each bulb is identical, we know that they must have the same resistance. Finally, we apply the equation for power output through a given resistance (in this case the light bulbs), which is P = I 2 R. This … WebThe brightness of a light bulb is related to the power dissipated by that bulb. Recall that power depends upon the square of the current that passes through the bulb and the resistance of the bulb. Since each light bulb in this circuit has the same resistance, the lightbulb with the largest current passing through it will be the brightest.
