Lightbulb A is marked "10.0 W 120 V," and lightbulb B is marked "60.0 W 120 V." These labels mean that each lightbulb has its respective power delivered to it when it is connected to a constant 120-V source. (a) Find the resistance of each lightbulb. (b) During what time interval does 1.20 C pass into lightbulb A? (c) Is this charge different upon its exit versus its entry into the lightbulb?
