H1P3: Poor Workmanship
Joe wants to heat his 12'X20' workshop with electric heat. He has hired the HACME electrician company to build the system. They propose to use three W 240V baseboard heaters to provide a total heating capacity of W. (A heater is basically a resistor. This is not quite true, because there is a thermostatic switch incorporated into the heater and because the resistance of a heater varies a bit with its temperature. But we will use a linear resistor as a model of a heater.)
In the proposed system the heaters are connected in parallel with the 240V 60Hz AC po
