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
Watts = Volts X Amps. Amps=Watt / Volts. So, with a 240V mains, a 60W bulb draws 0.25amps. On a 12 system (car/auto) a 60W bulb draws 5 amps. On a 110V mains, a 60W bulb draws .55 Amps.
The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.
The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

This has no physical meaning. The correct unit for power is the watt (not watt per hour).
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.
A 100 watt bulb uses 0.1 kilowatt (100 watts / 1000) per hour. At 15p per kilowatt-hour, the cost of running the 100 watt bulb for an hour would be 1.5p (0.1 kW * 15p).
Actually, your wrong. Sure, the lighting ithat is set for proper illumination is 60watts, but if anyone is used to using a dimmer, you can dial down the power consumption for a typical incandescent bulb and it will still light. And as expected, the light level will decrease as you lower the dimmer setting as well.
Typical home energy cost is 10 cents per kilowatt hour A 60 watt bulb running for one hour uses 60 watt hours .10 X (60/1000) = .006 cents per hour 16.66 60watt bulbs on for one hour would cost 10 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
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.
It depends on how much you use the light, and how much power costs in your area. You can find out the second by looking at your electric bill... it'll give the cost per kWh (kilowatt-hour). The difference between a 40 watt bulb and a 60 watt bulb is 20 watts, meaning you'd have to leave the light on for about two days straight for the savings to be even one kilowatt-hour, and if it were on all the time in a year you'd save 180 kWh or so... almost certainly less than $20.
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
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.
The energy used (work done, same thing) is 120 watt-hours, which is also 0.12 units or 120x3600 joules.
"A standard light bulb I would consider to be a 60 watt light bulb, and kilowatts are the amount of usage in a light bulb. From my research I have found that a standard 60 watt light bulb uses approximately 1.44 Kilowatts per hour."
60 watt-hrs= 60 watt*1 hr so it will take 1 hour.
