A light bulb has a resistance of 144 Ω and is designed for use with a 120 V power supply. What is the power output of the light bulb? If the bulb is accidentally connected to a 240 V power supply, what would be the power output of the light bulb? Why might this be dangerous? What resistance would be needed in a light bulb that works on 240 V so that it would have the same brightness as the original light bulb?
