To begin, you'll need to find your electric meter, which could be inside or outside of your home. Many electric meters these days are digital and pretty easy to read, but if you have an older "dial-type" meter, go to this electric meter reading guide to learn about how to read and understand it. For each of the two experiments below, you will first record three simple pieces of data in a table: 1) day and date, 2) time, and 3) the kWh reading from the meter. Then record the results of three simple calculations: kWh used: Calculate kWh used since the last reading (subtraction). Hours elapsed: Calculate the number of hours since the last reading (subtraction rounded to a whole number). Average kW used: (kWh used)/(hours elapsed). If this number turns out to be 0.36, for example, it means that your average household power usage for the time period was about 360 watts, the equivalent of running six 60-watt bulbs for that whole time period. a. Daily Electrical Usage: Data Collection Pick a convenient time of day to take readings from your electric meter. You'll need readings roughly a day apart, but if they differ by only an hour or two, that should be fine. Pick a consistent time you'll remember, though, such as after getting home for the day. You need to start by doing an initial meter reading, then follow up with a reading every day for the next 7 days. You'll do 8 readings in all. Record your readings in the tables below. In addition to the data fields described above, there is a lot of room for usage notes. Record anything that might have substantially affected the electrical usage since your previous reading. This might include the amount of time people were around and awake at home, use of specific devices such as an air conditioner, clothes dryer, TV, or lighting. Type your response here: Initial Reading day & date time kWh reading Day 1 Data Usage notes (since last reading) day & date time kWh reading kWh used hours elapsed To begin, you'll need to find your electric meter, which could be inside or outside of your home.
