Question: Lightbulb A is marked "40.0 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. R(40.0 W 120 V) = R(60.0 W 120 V) =

(b) During what time interval do 2.00 C pass into lightbulb A?

(c) Is the charge different upon its exit versus its entry into the lightbulb? Explain.

(d) In what time interval do 1.70 J pass into lightbulb A?

(e) By what mechanisms does this energy enter and exit the lightbulb? Explain.

(f) Find the cost of running lightbulb A continuously for 30.0 days, assuming the electric company sells its product at $0.110 per kWh.
