how much does a light bulb cost to run it per hour.?

Electricity is charged by the kilowatt (1000 watts) hour.  A 60 watt bulb uses 60/1000 hr. That's .06 times price per KWH.

Deppends on the bulb, and it's efficiency, total energy in = total out. 50W at 10 min is 30000 Jouls of energy.\nThe efficency of an average incad. bulb is about 15% efficient, so I would say you get about 4500J of light, and the rest would mostly be heat, about 25500J of heat.\n\nI am not sure how to convert the Jouls into Lumens, and Calories/BTUs, but it can be done.

Just one. But the light bulb really has to WANT to change...

I work with light bulbs and the light output is measured in C. lumens.

1000 watt system with turbine, charger, tower, batteries, inverter......$5000\nYou can make a system cost more or less.\nIf you are on the grid, dont bother.\nMIKE

Dude, \n\n   You have to reword your question. It really doesn't make much sense. Here's my interpretation of the question:\n\n"An AC voltage (230v/50Hz) is applied to a light bulb. If the frequency is reduced to 10Hz will the light flicker?"\n\nAnswer is yes. We do not see the 50Hz flicker, because of persistence of vision.

you need to know how much energy the appliance consumes, and the cost of that energy.  for instance:\n\nif i use a space heater, i can look on the back and see it is rated at 1500 Watts.  if i use it for 2 hours, then i have used 2*1500 = 3000 Watt-hours or 3 kilowatt-hours of electrical energy to power the space heater.\n\nif the power company sells me electricity at 5 cents per kilowatt-hour, which is pretty typical, then running my space heater for 2 hours costs 15 cents.

probably between 16- 23 per hour

If you use the mini fairy type of outside lights the cost will be minimal. Probably no more than 2-3 dollars for the next month. Get creative! Do some large bushes or small trees! Have a Great holiday! ;-)=

depends on the type of bulb, For incadesant bulbs thee is NO extra power required, they get hot, they glow. For florescent tubes it can be quite long, certainly of the orer of hours. once up and running they use very little

It depends on where you live.  The cost of electricity on the power grid ranges from about 4 cents per kilowatt hour in Kentucky to about 14 cents per kilowatt-hour in New York City.   You would need to find out what the cost per kilowatt hour is where you live and multiply that by the number of kilowatt-hours you would use in a month.\n\nTo determine the number of kilowatt-hours you would use in a month, multiply the power (in watts) of each appliance by the number of hours that appliance is being used and divide this by 1000.  For example if you use eight 100-watt light bulbs an average of 5 hours a day than, they would account for 8 x 100 x 5 x 30 (days in a month) = 15000 watts/1000=15 kilowatt-hours.  If you don't know how many watts the appliance uses, multiply the number of amps by the voltage the appliance uses; but it is easier just to check the table in the link below to find a typical power useage for each of your appliances.\n\nOnce you've totaled the number of kilowatt hours used (watts x hours used / 1000) for each appliance, multiply that total by the cost per kilowatt-hour in your area.\n\nThe biggest influences on your electric costs or usually the water heater and heat and air, and possibly the oven if it is used a lot.  Using a space heater a lot can effect it a lot.

Electric light is produced by running an electric current through a resistor that then glows white-hot.  Edison searched through thousands of different materials to find one that glows just right.\n\nToday most regular light bulbs use a tungsten filament (a little wire made of the material 'tungsten') which gives off a lot of light but it is relatively breakable.\n\nWhen a bulb 'burns out' it means that this little filament has burned up or broken.  It is more likely to break when it is turned on.  Technically I suppose you could get more life out of a bulb by leaving it on all the time but that would be a waste of energy and you don't want light all the time.\n\nThese days there are other materials and other ways to make light bulbs that last a lot longer but they are not in common usage yet.

On the average, approximately $23.00 per hour.  A lot has to do with the area you are located in and if it is in a hospital setting.  I hope that this helps you!

sure!\n\nWatch this...............(made ya look)\nno, seriously, "How many Americans does it take to change a light bulb?"........." "1 billion and 1. 1 to put the bulb in and a billion troops to enforce a democratic change of government for as long as it takes."

to run a house about $5,000.  to add everything else to because it produces DC power (like a battery) and a house used AC power: $50,000 and another $10,000 for engineering, and $5,000 for somebody to install it all for a total of about $70,000 given that the average house power bill is about $100-200 it would take about 30-60 years to break even (not including maintainence costs and its an unreliable power source).  Moral of the story...just buy power from the utility!

There are 24 x 31 = 744 hours in a 31 day month.  Check your fan name tag for the rated watts (single speed?).  Multiply the watts times 744 and divide by 1,000 to get KW-Hr (kilowatt-hours) of power per month.  Check your power bill for the charge per KW-Hr.  It should be about 10 to 15 cents per KW-Hr (or KWH), depending upon where you live.  For example if a small fan draws say 20 watts, the calculation would be:\n\n(20 x 744)/1,000 = 14.88 KW-Hr @ $0.10 per KW-Hr = $1.49 per month or about $17.85 per year.\n\nGood luck.

Hey, Benni.  When I was interning in the power industry I had to review some electric bills for a rather large office in downtown Chicago.  They were on the order of tens of thousands of dollars per month.  And this was not anywhere near what a stadium would use.\n\nI'll try to find some figures for you and will edit this post with sources when I find them.  Note that, for indoor stadiums, the cost will be much higher because of heating/cooling.\n\nUpdate: Below is the site of a stadium that says its bulbs are 1500W each.  Each pole looks to have about 12 bulbs.  There looks like there are at least 8 poles.  That's 144kW in lighting.  Assuming they're on for 5 hours a night, that's 720 kWh just in the lights every night that they're turned on.  At $0.05/kWh (they probably get a better rate than that), that comes to $36,000 per night.  Note that that doesn't include ANY other power sources, but is still a highly speculative number.  I'll let you know if I can find anything more definitive.\n\n2nd Update:  The Baltimore Ravens' stadium has two jumbo screens that can consume up to 80 kW.\n\nFinal Update:  The New York Giants' stadium consumes enough power to run 4,000 homes on gameday.  Assuming a typical home uses 800 kWh / month, that is about 1 kW at any given time, which means their stadium uses about 4 MW on gameday.  Assuming this lasts for 5 hours, that's 2000 kWh in one day.  Not a bad number with the above lighting (for a smaller stadium) listed at 720 kWh...  At $0.05/kWh, that's $100,000 every game.  I also came across a site which said Penn State university's electric bill is over $1 million each month.\n\nUpdate on your question:  My above calculation is incorrect.  If a stadium uses 4 MW on gameday for 5 hours, it uses 20,000 kWh on that day, which is then $1,000 at $0.05/kWh.  I think the number is conservative, though.  Sorry for the misunderstanding!
