Textbook Question
Chapter 11, Problem 3ICA
There is a large push in the United States to convert from incandescent light bulbs to compact fluorescent bulbs (CFLs). The lumen [lm] is the SI unit of luminous flux (LF), a measure of the perceived power of light. To test the power usage, you run an experiment and measure the following data. Create a proper plot of these experimental data, with electrical consumption (EC) on the ordinate and LF on the abscissa.
| Electrical Consumption [W] | ||
| Luminous Flux [lm] | Incandescent 120 V | Compact Fluorescent |
| 80 | 16 | |
| 200 | 4 | |
| 400 | 38 | 8 |
| 600 | 55 | |
| 750 | 68 | 13 |
| 1250 | 18 | |
| 1400 | 105 | 19 |
