A 1-watt bulb uses 3600 watt-hours every hour, which is 1/1000 of a kilowatt-hour, so the cost is 0.01 cents.

How much will it cost to run a 100 watt light bulb for one hour if electricity costs ten cents per kilowatt hour?
1 cent
Which type of bulb is more efficient incandescent or fluorescent?
A typical 20-watt compact fluorescent light bulb can produce about as much light as a 100-watt incandescent light bulb. There is an 80 per cent improvement in efficiency.
How much does it cost to run a 60 watt light bulb for 1 hour if electricity costs 10 cent per kilowatt-hour?
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
How much does it cost to run a 60-Watt light bulb for one hour?
If your electricity costs 10 cents per kilowatt-hour, it would be about 0.6 of a cent per hour, or about 14.4 cents per day.
How much does of 1 amp of electricity cost?
It depends what your voltage is and how much your electricity costs. Assuming you are running standard residential voltage and your electricity costs 10 cents per kilowatt-hour. 1 Amp would cost you 1 cent per hour or 29 cents per day or $105 per year.

How much does it cost to run a compact fluorescent bulb?
It depends on the bulb's wattage (its actual wattage, not the incandescent equivalent) and the cost of electricity where you're using the bulb. For example, suppose you have a CFL that draws 14 watts and electricity in your area costs 12 cents per kilowatt-hour. Using very rough approximations, in one hour your bulb would use about 1/70 of a kWh (1000/14 = 71.3), so the bulb would cost about 1/6 of a cent (12/71) to operate for an hour.
What are facts on the light bulb?
1 The light bulb was invented in 1879 by Thomas Alva Edison. 2 When you turn on a light bulb only 10 per cent of the electricity used is turned into light, the other 90 per cent is wasted as heat. 3 In the UK we waste £140 million a year by leaving our lights switched on unnecessarily - this causes 900,000 tonnes of CO2 emissions, enough to fill 180,000 hot air balloons! 4 Low energy light bulbs last on average up to 12 times longer than traditional fluorescent bulbs. 5 Each low energy light bulb you install in your home could save you as much as £9 per year in energy costs, or £100 over the bulb's lifetime 6If every UK household installed just three compact fluorescent light bulbs in place of traditional bulbs, enough energy would be saved in a year to supply all street lighting in the UK 7 UK households use £1.9 billion worth of electricity every year on lighting 8 Energy efficient bulbs last up to 12 times longer than their inefficient counterparts 9 A heavy coat of dust can block up to half of the light 10 If everyone installed one energy-saving light bulb the carbon dioxide emissions saved would fill the Royal Albert Hall nearly 2000 times. Hoped this helped! :)
Is a cent an insulator?
A conductor. A US one-cent coin is made of a copper alloy, which is a good conductor of both heat and electricity.

How much energy does London underground use?
London underground's electricity consumption in 2007 and 2008 was 0.4 per cent of all the electricity used in the UK and 2.8 per cent of London's total usage. The total annual electricity consumption is just over one terawatt hour each year. cheers ... Skunkfarmer . New Hampshire USA
Are halogen bulbs more energy efficient than traditional incandescent bulbs?
If you are asking if, for the same wattage, a halogen bulb produces more light output than a traditional incandescent bulb, the answer is yes.This means that, to get a given amount of light, you can sometimes use a lower wattage halogen bulb than what you would need to use if it were a traditonal incandescent bulb.So another answer to your question is yes, you can save money on the running cost for electricity if you use a halogen bulb which has a lower wattage than the traditonal incandescent bulb.However, to be able to use the halogen type, you might have to change the bulb-holder and shade used in your present light fitting!NoteWe pay for the total energy consumed, not for the current taken by any particular sorts of bulbs - or indeed any types of appliances - whilst they are being used.The cost of the energy used is calculated in units of kilowatt-hours at whatever charge is relevant for the time of day, all according to the agreement you have with the energy supplier in your area. (Usually an energy utility company.)For the full details of the costs and charges made by the utility company that supplies your area, just read one of your electricity bills.If you pay 20 cents per kilowatt-hour (kW-h) of energy and you use a 50 watt bulb for one hour, you'll pay for (50 x 20) / 1000 cents, which equals just 1 cent - no matter what type of lamp you use. In particular it is worth noting that the bulb's voltage doesn't come into this calculation.
