Textbook Question
Chapter 1, Problem 26R
You will learn in Chapter 3 that residential lighting loads are based on 3 volt-amperes per ft2 (33 volt-amperes per m2). Determine the minimum lighting load required for an area of 186 m2. Do calculations for both feet squared and meters squared so you can see the difference in answers. To convert meters squared to feet squared, refer to Table 1-8.
