A very speculative average:

Average plasma: 338 watts

Average LCD: 176 watts

Some comparisons to give you relative idea:

PlayStation 3: 197 watts

Xbox 360 Elite 185 watts

Nintendo Wii: 19 watts

DirecTV HR20 DVR: 33 watts

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 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 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 much does it cost to run a 50inch plasma tv per hour?

The cost to run a 50-inch plasma TV per hour typically ranges from $0.15 to $0.30, depending on the TV's wattage and your local electricity rates. Plasma TVs often consume around 150 to 300 watts of power. To calculate the exact cost, multiply the wattage by the hours of use and then by your electricity rate (in kilowatt-hours). For example, if a TV uses 200 watts and electricity costs $0.12 per kWh, it would cost about $0.24 per hour to run.

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 joules for a 52 inch screen tv?

The energy consumption of a 52-inch TV can vary based on its technology (LCD, LED, OLED) and usage. On average, a 52-inch LCD TV consumes around 100 to 200 watts per hour. Therefore, if you want to convert this to joules, you can use the formula: energy (Joules) = power (watts) × time (seconds). For example, a 150-watt TV used for 1 hour would consume approximately 540,000 joules (150 watts × 3600 seconds).


How many volts per hour when they say 800 watts?

There is no valid conversion.
