Well, isn't that a lovely question! A 100-kilowatt power system can typically provide enough energy for about 20-30 homes, depending on their energy usage. It's amazing to think about how we can harness the power of nature to bring light and warmth to so many families. Just imagine all those homes glowing with happiness and energy!
First let us convert the power of the bulb into kilowatts.A kilowatt is 1000 watts. We have one tenth of that. So 100W = 0.1kWTo work out the kilowatt hours we simply multiply the power in kilowatts by the time the bulb is on for (in hours):0.1kW x 10h = 1 kWha 100 watt bulb uses 100 watts of power. In ten hours it uses 100x10 watt-hours, or 1 kilowatt-hour. A kilowatt-hour is also called a unit, and units are what you pay for.
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.
You could power ten 100 watt light bulbs.
kWh = Power(kW) x Time (hours)AnswerA kilowatt hour (symbol kW.h) is a unit of measurement of electrical energy.
I would have to guess, 100 watts. Power consumed is equal to P I E. P = Amps (I) X Volts (E). Power is measured in watts, or typically, as read on your energy bill, Kilowatts (kw, where 1 Kw = 1,000 watts). So, 100 watts/120V (which is the typical American system) = 0.833 amp (I). Your typical power meter, by which the power company reads your monthly bill, measures amps. Also, 100 watts is 1/10 Kw, or 0.10 kw/hourAnswerFirst of all, you do NOT consume power; you consume energy. Energy is measured in joules, so power is measured in joules per second, which is given a special name: the watt.So there is no such things as 'watts per hour', as this would mean 'joules per second per hour' which, obviously, is nonsense!So, your question should ask, "How much energy is consumed by a 100-W lamp in one hour?" Well, if one watt represents one joule per second, then the lamp will consume 100 x 60 joules in one minute and, therefore, 100 x 60 x 60 joules in one hour. That is, 360 000 joules.Electricity companies usually measure energy in kilowatt hours, rather than in joules. A kilowatt hour is defined as "the energy consumed, in one hour, at a rate of one kilowatt'. You can think of a kilowatt hour simply as being a very big joule! Since 100 W is 0.1 kW, we can therefore say that the lamp must consume 0.1 x 1 = 0.1 kilowatt hours during a period of one hour.

You could power ten 100 watt light bulbs.
1 kilowatt is equal to 1,000 watts, so a 100 watt bulb uses .1 kilowatt. Technically, your home or business meter base measures kilowatt hours, meaning that it measures both the kilowatts and the amount of time. If you turn on 10 100 watt bulbs for 1 second, that would be a kilowatt, but the amount of power use would be insignificant. So... To calculate the kilowatt hours: .1 kilowatts (from above, knowing the energy use of the bulb) Multiplied by 24 hours in a day Multiplied by 30 days... .1(kilowatts) * 24(hours)* 30(hours in a day) = 72 kilowatt hours

Your question shows the importance of using the correct symbols, because your symbols are incorrect and, therefore, your question is confusing.So, are you asking how many milliwatts (mW) there are in a kilowatt (kW), or are you asking how many megawatts (MW) there are in a kilowatt(kW)?Notice that the symbol for a watt is an upper-case W. The symbol for a milli is a lower-case m, and the symbol for a mega is an upper-case M.If the former, then there are one-thousand milliwatts in a watt, and there are one-thousand watts in a kilowatt, so there must be one-million milliwatts in a kilowatt.If the latter, then there are one-thousand kilowatts in a megawatt, so a megawatt must be one-thousandth of a megawatt in a kilowatt.
Remember that 1 kW = 1000 W So 100 / 1000 = 0.1 100 W = 0.1 kW You take the power - the wattage of the lamp, and multiply with how long it is lit. A 100 W bulb - 0.1 kW - will use 0.1 kWh in one hour. Or 1 kWh in 10 hours. Or 10 kWh in 100 hours.
kWh = Power(kW) x Time (hours)AnswerA kilowatt hour (symbol kW.h) is a unit of measurement of electrical energy.
divide by 100
Most televisions run between 100 watts to 400 watts.That is less than a kilowatt.100 watts is 0.1 kilowatt400 watts is 0.4 kilowatt
