A1500-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.
