A heater dissipates 1200 W  of power when it is connected to a 190 V  battery. What current will flow through the heater when it is connected to the battery? 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 that is 5.00 m  × 8.00 m ﻿ × 10.0 m ﻿ by 10.0∘C? Note that the specific heat of air is 1006 J/(kg⋅∘C) and the density of air is 1.20kg/m3.
