You want to heat your small garage using a couple of electric radiators. The
power and voltage requirements for each radiator are 1200 W, 240 V. But
you are not sure how to wire the radiators to the power supplied to the
garage. Should you use the wiring diagram on the left or the one on the right?
Does it make any difference?
Once you have studied the material in this chapter, you will be able to answer
these questions and determine how to heat the garage. The Practical
Perspective at the end of this chapter guides you through the analysis of two
circuits based on the two wiring diagrams shown below.
