5) A 1500 W electric hair dryer is designed to work in the UnitedStates, where the AC voltage is 120 V rms. What power is dissipatedin the hair dryer when it is plugged into a 240 V rms socket inEurope ?
10) A hair dryer has a power rating of 1200 W at 120 V rms. Assumethe hair dryer circuit contains only resistance.
a) What is the resistance of the heating element ?
b) What is the rms current drawn by the hair dryer ?
c) What is the maximum instantaneous power that the resistance mustwithstand ?
