Lightbulb A is marked "40 W 120 V", and lightbulb B is marked "75 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. R(40 W 120 V) = Ω R(75 W 120 V) = Ω (b) During what time interval does 2.30 C pass into lightbulb A? Δt = s (d) In what time interval does 3.00...
