1/10 killowatt per hour (.1kwh). Multiply your utility provider rate by .10 to obtain your answer.
Example - $0.12 per kwh multiplied by .10 = 1.2 cents per hour.

There is no such thing as a 'kilowatt per hour'; the correct unit is the 'kilowatt hour'. A 100-W lamp is equivalent to 0.1 kW so, if it operates for one hour, then it consumes 0.1 kilowatt hours (kWh) of energy. At, say, 12 cents per kilowatt hour, this equates to 1.2 cents.
Yes, a 100 watt bulb produces more heat than a 25 watt bulb because the higher the wattage, the more energy is being converted into heat. In this case, the 100 watt bulb will generate more heat compared to the 25 watt bulb.
A 20 watt incandesent bulb is dim. For a medium sized room you need 100 watts. A 20 watt halogen bulb is brighter but still quite dim. These are marketed as low-energy but they are not. For a medium sized room you need 80 watts. A 20 watt fluorescent bulb can light a medium sized room quite brightly. This is a genuine low energy bulb.
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
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.
energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit energy consume by the bulb = P*time =100*6 wh =.6 kwhour=0.6 unit
Yes it can provided the volotage is right, because for a bulb the volt-amps are equal to the watts - if it is an incandesent bulb. For a fluoresecent bulb the power-factor must be better than 100/150 or 0.67.
Almost twice as much as 100 is almost twice 60.
The main difference between a 100-watt and a 75-watt light bulb is the amount of light output they produce. A 100-watt bulb will be brighter and consume more energy compared to a 75-watt bulb. The 100-watt bulb may also generate more heat than the 75-watt bulb.

An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.

The brightness level of a 25 watt LED bulb is equivalent to that of a 100 watt incandescent bulb.
A 40 watt bulb is dimmer than a 100 watt bulb.
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
100
Yes. It just won't be as bright.
