1. The problem statement, all variables and given/known data The question asks for us to go around our house, figure out the power usage of different devices, based on the estimated time use of these devices and calculate the total power usage per month. 2. Relevant equations Energy = Power X Time Power = kW Time = hours 3. The attempt at a solution Example Samsung TV Power usage @ 130.65W Usage @ 60 minutes per day (1 hour) (0.13065 kW)(1 hour) = 0.13065 kWh (0.13065 kWh)(31 days) = 4.05015 kWh per month Is that the correct way in trying to determine a given devices power consumption per month ?
