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...
A 1500 W electric heater is plugged into the outlet of a 120 V circuit that has a 20 A circuit breaker. You plug an electric hair dryer into the same outlet. The hair dryer has power settings of 600 W, 900 W , 1200 W, and 1500 W. You start with the hair dryer on the 600 W setting and increase the power setting until the circuit breaker trips. Under what setting does the circuit breaker trip. Please, no...
