∙ 11y agoYou can find the power of your television set on its data nameplate. Power is the rate at which it will consume energy, so the number of watts is not affected by time. If, for example, it is rated at 300 W, then it's 300 W whether you use it per hour, per day, per week, per month, or per year! Power is simply a rate; the rate at which you consume energy.
Because power is a 'rate', your question is rather like asking "How many miles per hour does my car do per hour?", when your question should be "How many miles will I drive in one hour, at so-many miles per hour?".
So you should be asking, "How much energy will a television set consume per hour?" As your electricity company charges you for energy measured in kilowatt hours, a 300-W television set would use 0.3 kilowatt hours in one hour, 0.6 kilowatt hours in two hours, and so on.
A kilowatt hour is the amount of energy consumed, per hour, at the rate of one watt.

How many watts does a 54 inch television have?
you have to know how much voltage it is plugged into and how many amps it consumes. voltage x amps = watts. Look on the electrical plate on the back of the TV. for example in the US it might be 120 volts x 5 amps = 600 watts or .6 kilowatt hour (about 6 cents per hour). This tells you how much electricity the TV uses, not how many it has.
How many watts does a charger use per hour?
about 15 per hour its not a lot
How many watts required for normal television?
Watt is a unit of power, or energy per time. Therefore, "watt per hour" is wrong: While the TV is on, it uses so-and-so many watts (or Joules/second), while it is off, it doesn't. TVs vary widely in their usage; CRTs (the big bulky ones) use more than the modern flat-screen TVs. Look at the back of your TV for electrical specifications. Perhaps you want to know how much you spend an hour. 200 Watts (for example) is the same as 200 watt-hours per hour, or 0.2 kilowatt-hours per hour. To convert this into money, look at a bill from the power company to see how much you spend for every kWh.
How many kilowatts does a TV use in a hour?
What you meant to ask is 'How many watts does the average TV use?' The answer is usually in the range of 80 to 200 for a flat screen TV and rather higher for an old CRT TV. The number of kWh it consumes depends entirely on how many hours it is switched on, not forgetting to take into account and current used on standby.
How many watts does an average printer use?
about half as many watts as the computer per hour a computer uses 200-500

How many volts per hour does a 75 kva transformer produce?
Volts per hour is an invalid statement. You may have meant Watts per Hour.
How many watts does an average printer use?
about half as many watts as the computer per hour a computer uses 200-500
How many kilowatts per hour does a flat screen tv use?
None. There is no such thing as a 'kilowatt per hour'. If, on the other hand, you are asking how many 'kilowatt hours' a flatscreen television uses, simply look at its nameplate to find its power rating in kilowatts (more likely, it's in watts, so you need to divide by 1000), and multiply it by 1 to find the number of kilowatt hours consumed over a period of one hour.
How many volts per hour when they say 800 watts?
There is no valid conversion.
If a television uses 475 watts how much is that a year in energy costs?
To answer this question two more factors are needed. One is how long is the television on in a 24 hour period and the second is the amount that you pay per kilowatt hour on your electricity bill.
How many kilowatt-hours do 50 w used for 12h equal?
A Kilowatt hour is 1000 watts per hour. A 50 watt bulb will use just 50 watts per hour. Therefore over 12 hours the 50 watt bulb will use 50*12 watts = 600 watts or 0.6 of a kilowatt hour.
