A 1500-W heater is designed to be plugged into a 120-V outlet.
What current will flow through the heating coil when the heater is plugged in? I = A
What is R , the resistance of the heater?
How long does it take to raise the temperature of the air in a good-sized living room 3.0m x 5.0m x 8m by 10 degrees C? Note that the specific heat of air is 1006 J/(kg x degrees C) and the density of air is 1.20 kg/m^3.
