a) A hair dryer draws 9.5 A when plugged into a 120 V line. Calculate the resistance of the hair dryer, and how much charge passes through it in 15 minutes, assuming a direct current. b) An electric clothes dryer has a heating element with a resistance of 8.6 N. Calculate the current in the element when it is connected a 240 V power source.
