"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.
power=energy*time
therefore, power consumed=60*10=600W
The energy used each hour is 60 watt-hours.
To find the energy in Joules you multiply power in Watts by time in seconds.
So the sum is 60 watts x 36,000 seconds, or 2,160,000 Joules
60W * 8h= 480 watt*hours.
6o Wh = 216000 J
30 cents
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 bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
It depends how much you pay for electricity. A 15 Watt bulb would consume around 134 kWh of electricity. In the UK, electricity is around 10p a kWh, so it would cost £13.40 to run the bulb.
The actual cost will depend on the charge by your supplier. It can be calculated by finding the cost of 15% of one unit of electricity (kw hour)
A watt is a measurement of electricity, usually pertaining to light. Light bulbs luminosity is graded by wattage, such as a 60 watt bulb, 100 watt bulb and so on. You would find a watt in a light bulb, to start.

A 75 bulb will use more electricity.
You have to pay for the work (enegy) of 150 watt hours. Scroll down to related links and look at "watt-hour - Wikipedia".

Per hour the answer is 400 watt-hours or 0.4 kW-hours (or units).
A 60W bulb will use 60W X 1 hour / 1000. this will give you the KWh - the units your electricity company uses to charge you.So 60 X 1 =6060/1000 =0.060 Kwh
No. Watt is the measurement of how much electricity.
A 40 watt bulb uses 40 watt-hours in an hour, which is 0.04 kilowatt-hours, so it would take 25 hours to use 1 kilowatt-hour or 1 unit.
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.
