Day 7 Data Usage notes (since last reading) day & date time KWh reading KWh used hours elapsed avg. KW used b. Usage Extremes: Data Collection For this experiment, you'll measure electrical usage during a time period when you expect to have very light electrical usage (for instance, while you're asleep at night or during the day when no one is at home). Likewise you'll measure electrical usage during a time period when you expect to have heavier than average electrical usage. This time period might be in the evening, when lights and other appliances are on. Both of these time periods should be at least 4 hours long, to increase the accuracy of your results. Record your results in the tables below for each situation. For each time period, you'll need to take an initial and a final reading.
