Room Heater
(a) What is the rms current drawn by a room of 4500 W electric heater during the execution of 120 V rms?
(a) What current effective is drawn by a 4500 W electric room heater when operating on 120 V rms? (b) What is the power dissipated by the heater when the voltage down to 105 V rms at a brown-out? Suppose that the resistance remains the same.
lol Physics 221 is terrible because it is for all majors who do not need to know physics. I know I am inside. = F (a) 4500/120 = 37.5 A (b) [37.5 (105/120)] x (105) = 3.445 kilowatts
