Refrigerator----- 8.3 Amps x 120 V = 1,000 W (rounded to nearest whole number)

Run time- 24 hr x 3600 = 86400 seconds

Energy- 86400 sec x 1000 W = 86400000 J

Convert to kWh- 86400000 J/3600000 = 24 kWh

Energy Cost- 24 kWh x .1 = $ 2.40

 

Laptop----- 3.3 Amps x 120 V = 400 W

Run time- 6 hr x 3600 = 21600 seconds

Energy- 21600 sec x 400 W = 8640000 J

Convert to kWh- 8640000 J/3600000 = 2.4 kWh

Energy Cost- 2.4 kWh x .1 = $ 0.24

 

AC----- 125 Amps x 120 V = 15000 W

Run time- 8 hrx 3600 = 28800 seconds
