Trials
On January 21 2007, the experiment was done. In the first test, there were three trials for twenty-seven appliances. On the first trial, an older meter was used to test the appliances but it appeared that the low levels measured were inaccurate. This was overcome by using a different newer meter, which happened to be battery powered and isolated. This meter worked much better and the meter proceeded to measure every appliance. To be sure that the same reading was recorded, all appliances were tested twice.
Formula
Miliamps * 1 amp/1000 miliamps*120 volts = watts
Watts * 1 kilowatt/1000 watt * 3600 hours/year = kilowatt-hour/year
$/kilowatt-hour * kilowatt-hour/year = $/year
