In a household, a 120-W personal computer (PC) is run for 4 hours per day, while a 60-W bulb runs for 8 hours per day. If the utility company charges $0.12/kWh, calculate how much the household pays per year (365 days) for the PC and the bulb.
Added by Adrian O.
Step 1
The power rating of the PC is 120 W, and it runs for 4 hours per day. Energy consumption (in watt-hours) = Power (in watts) × Time (in hours) Energy consumption of PC per day = 120 W × 4 hours = 480 Wh. Show more…
