Lightbulb A is marked “25.0 W 120. V,” and lightbulb B ismarked “100. W 120. V.” These labels mean that each lightbulbhas its respective power delivered to it when it is connected toa constant 120. - V source. (a) Find the resistance of each lightbulb.(b) During what time interval does 1.00 C pass into lightbulbA? (c) Is this charge different upon its exit versus its entryinto the lightbulb? Explain. (d) In what time interval does1.00 J pass into lightbulb A? (e) By what mechanisms does thisenergy enter and exit the lightbulb? Explain. (f ) Find the costof running lightbulb A continuously for 30.0 days, assumingthe electric company sells its product at $0.110 per kWh.
