In the sense of 'work' as force moving through a distance, a light bulb does none
of that.
But in the sense that mechanical work is equivalent to energy in other realms,
the 75-watt light bulb consumes 75 joules of electrical energy every second,
and radiates 75 joules per second of energy in the form of light and heat.

What it is the difference between 100 watts and 75 watt light bulb?
25 watts?
True or false a three way light bulb has 3 filaments?
False. They contain two filaments which are first switched on independently of one another (the lowest two settings), then switched on simultaneously to produce the highest setting. For instance a bulb containing a 25 watt filament and a 50 watt filament will produce 25, 50 and 75 watts of light.
How long does it take to do 432 joules of work with 75 watts of power?
A watt is equal to 1 Joule per second. So 432 Joules * (1 / 75 Joules per second) = 432/75 = 5.76 seconds.
How much electrical energy does a 40w light bulb use if it is left on for 12h?
75W means bulb which give 75W power when connected to domestic light. Power is nothing but energy per second. Thus energy consumed by bulb can be calculated as follows. E = 75*60*60*4J = 1080kJ
How much energy is used if 500 watts of power is left on for 5 hours?
A kilowatt hour is equal to the amount of electrical energy consumed at a rate of one kilowatt. 1 kilowatt hour is the same as 1000 watt-hours.So using that principle. A 500 watt microwave will consume 500 watt-hours in an hour, or 0.5 kilowatt-hour.CommentIn practice, it's difficult to determine an answer to your question, because microwaves don't operate continuously but, rather, in short bursts. Without knowing the cycle rate of each burst of energy, it's impossible to come up with a definitive answer.
How many 75 watt fluorescent bulbs are needed to give as much light as a 75 watt incandescent bulb?
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
Which would use more energy a 50 watt bulb or a 75 watt bulb?
A 75 bulb will use more electricity.
Can I use a 60 watt bulb in a 75 watt bulb ceiling fan?
Yes.
How much time is required for an operating 75 watt light bulb to dissipate 10 joules of energy?
1 Joule = 1 Watt.sec, ie 1 Watt for 1 second. A 75 Watt bulb dissipates 75 Joules every second, so the answer is 10/75 of a second = 0.1333 seconds
How hot does a 75 watt reptile basking bulb get?
It depends on the bulb
How much current does a 75 watt light bulb draw from a 120v wall outlet?
It's 75/120 and the answer is in amps.
How bright is 1000 lumens?
It is equivalent to a 75 watt incandescent bulb
How many watts per hour does 75 watt bulb use?
The bulb's power, 75 watts, is the power it uses continuously all the time it is switched on. The energy it uses can be measured in watt-seconds (Joules) or in watt-hours. A 75 watt bulb uses 75 watt-hours each hour, which is 0.075 kilowatt-hour.
Can you use a 75 watt light bulb on a lamp rated 60 watt max?
Usually the 60-watt limit is used to prevent the lampshade overheating, so a 75-watt bulb should not be used. But if more brightness is required, try a low-energy bulb because a 15-watt one gives the same light as a 75-watt incandescent (old-style) bulb. Or a 20-watt would be even brighter.
Do 60 watt bulbs work in 75 watt lights?
Yes.
Would a 100 watt spot bulb and a 10 gallon heat Mat be too much heat for a baby ball python?
Yes, it would be. I use a 75 watt heat bulb in an 110 qt tub for my boa constrictor, and it keeps it a cozy 95 degrees. A 50 watt bulb with a UTH for your cage should be sufficient.
How many amps in a small table lamp?
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
