A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.

What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficientso a 12W will give about as much light
Can you use a 13 watt CFL bulb in place of a 60watt incandescent bulb?
no because it would blow up because the socket would draw 13 watt not 9 watt
Why do you have a light bulb?
Light bulb provide electrical light.
How many kilo jouls are there in a bread?
A slice of bresd contains 403kj
Is a light bulb considered a fixture?
A fixture is what the light bulb goes into.
Meaning of 60watt's in 60watt's bulb?
60 Watts is the amount of electrical power the bulb uses when it is switched on.
What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficientso a 12W will give about as much light
Can you upgrade a 60watt halogen bulb to a 75watt halogen bulb for a shift3 entetainment projector?
yes you can
Can you use car bulb 60watt on 12 volt 7.2 amp battery?
Yes if it is a 12 volt DC bulb.
What is the current in an ac circuit with 120volts and a 60watt light bulb?
Power = Current * Voltage Current = Power / Voltage Current = 60 W / 120 V Curretn = 0.5 A
Will a 60watt light bulb melt a chocolate?
Under the right circumstances, yes. So will, for example, a 15 watt soldering iron. It just won't melt very much. It is not the wattage that determines the temperature, it is the insulation (or lack thereof) around the bulb and chocolate that determine it.
What is measured in jouls?
Energy.
Can i light a light bulb with a battery and a paper clip?
Yes, if your battery has the capacity to match the light bulbs requirements. A 1.5volt "AA" battery cannot supply enough power to light a 60watt bulb. A flashlight that uses a single battery will have a bulb small enough to be powered by a small battery and a paper-clip as a conductor. A low voltage LED may also be used. Touch one end of the battery to one terminal on the bulb, and connect the other end of the battery to the other terminal using the clip. (you may find it helpful to use tape to hold it all together)
How much wattage is in a CFL?
So to replace a traditional 60-watt bulb, buy a 15-watt CFL: 60-watt incandescent / 4 = 15 watts. Note: Some brands of 60-watt equivalent CFLs still do not seem to give off as much light as a 60watt incandescent bulb.
What is the effiency of 60watt bulb run on a 100joule?
"60 watts" means "60 joules every second". That's what a '60 watt' bulb is designed to consume. If you put 100 joules of energy into a light bulb, 100 joules of energy are going to come out of it, one way or another. Either that energy will be converted into light and heat by the bulb's filament, or else it won't get consumed at all, and it'll come out the other side of the bulb and still be available for use in some other device. So, comparing output energy to input energy is not an effective way to evaluate the efficiency of a light bulb. What you need to do, in order to compare the economy and effectiveness of light bulbs, is to compare LIGHT output to input ENERGY.
Si unit for heat?
Jouls.
How many Jouls are in an apple?
about 500
