1. The problem statement, all variables and given/known data Lightbulbs labeled 40 W, 60W, and 100 W are connected to a 120 V/60 Hz power line as shown in the diagram. What is the rate at which energy is dissipated in each bulb? 2. Relevant equations Pr = (Vrms)^2/R 3. The attempt at a solution I'm not exactly sure how to get this one started. Do I have to make some sort of equivalency lightbulb? Can somebody please point me in the right direction?
