PHYSICS!! A computer monitor uses 1.5 A of current when it's plugged into a 120 V outlet...?
-
The monitor is never turned off. What is the yearly cost of operating the monitor if the cost of electricity is $0.14kWh
-
Answer:
120*1.5= 180 watts. 180*24= 4,320 watt-hours or 4.320 kilowatt-hours per day. 4.320*365= 1576.8 kilowatt-hours per year. 1576.8*0.14= $220.75 per year.
