Running a power of 60 watts for one hour uses 60 watt-hours of energy. If you run it for two hours, that would be 120 watt-hours.
Running a 60 watt appliance for 16 hours and 20 minutes is 1000 watt-hours, or 1 kWh, also called one Unit.
You multiply the watts by the seconds. 10 hours is 36,000 seconds, so the watt seconds is 60 x 36,000 Answer 2,160,000 watt-seconds You can also say the bulb uses 60 x 10 or 600 watt-hours.
A kilowatt is 1,000 watts. A 60 watt bulb uses 60 watts in an hour. So, in half an hour it uses 30 watts. Now if a kilowatt costs 20 cents, what does 0.03 kilowatt cost?
2300 watt-hours for every hour it operates. Watts x Hours = watt hours.
Watts is Watts and has no relation to time. w=v*a (west Virginia varsity). A 60 watt light bulb is 60 watts regardless of how long it is on. Watt hours would be what PG&E bills you for.
1 kilowatt-hour is 1000 watt-hours and 60 watt bulb consume during 1 hour 60 watt-hours of electricity, so then it costs 0.6 cent =>60/1000=0,06*price of 1 kilowatt-hour = 0.6 cent

60 watt-hrs= 60 watt*1 hr so it will take 1 hour.

60 days is 24x60 hours, so the energy used is 60x24x60 watt-hours, 86400 watt-hours or 86.4 kilowatt-hours or units. If it is a 60-watt incandescent bulb it could be replaced by a 12 watt low-energy bulb, and in the same time that would use only 17.3 units, saving 69 units costing about £10.
1 kilowatt-hour is 1000 watt-hours and 60 watt bulb consume during 1 hour 60 watt-hours of electricity, so then it costs 0.6 cent =>60/1000=0,06*price of 1 kilowatt-hour = 0.6 cent
The idea is to divide the energy by the power used. First, convert the units to make them consistent. For example, you might convert kilowatt-hours to watt-hours.
1 Watt means 1 Joule per second, so 60 watts means 60 Joules per second. A light bulb that burns energy at that rate for 3 seconds uses 180 Joules.
A 60 watt light bulb uses 60 watts of power in a period of one hour or 60 watts in one minute or 60 watts in one second or 60 watts during any period of time.How much total energy a 60 watt light bulb "consumes", which is the amount of electricity that has to be paid-for, is measured in watt•hours (that's watts times hours). So a 60 watt bulb consumes 60 watt•hours in one hour, or 60 Wh x 24 hr/day = 1440 Wh per day.That is the same as 1.44 kilowatt•hours (kWh), so, if you look up what your electricity supplier charges for 1 kWh you can figure out how much it would cost you in money. If 1 kWh costs you 25 cents, then leaving a 60 watt light bulb switched on for 24 hours straight would cost you 1.44 kWh x 25¢/kWh = 36 cents.
There are about 8760 hours in a year, so running a 60 watt bulb for a year would consume (60 times 8760) or 526000 watt hours. Electric power rates vary, but at $0.15 per kilowatt-hour, that would be almost $80.
"Kilowatt" is a rate of using energy. It's not an amount of anything.A 60-watt bulb uses energy at the rate of 60 watts ... the same as 0.06 kilowatts.In one hour, it uses 60 watt-hours of energy ... the same as 0.06 kilowatt-hours.
