1. What is the rate of heat production of a device with a resistance of 0.20 2 as a 10-A current flows through it? 2 A flat iron has a resistance of 0.40 2, and a 65-A current passes through it. Solve for the rate of heat production by the flat iron. 3. An electric stove receives an electric power of 1 500 W when 14-A current is supplied through it. How much is the resistance of the stove?
