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 an lg LCD television use?
Depends on the size of the TV. Between 50 to 150 watts is average.
A flat-screen television uses 3 amps and has a power rating of 300 watts. How many volts does it need?
To find the voltage required for the flat-screen television, you can use the formula ( V = P / I ), where ( P ) is the power in watts and ( I ) is the current in amps. Plugging in the values, ( V = 300 , \text{watts} / 3 , \text{amps} ), which equals 100 volts. Therefore, the television needs 100 volts.
How A flat-screen television uses 3 amps and has a power rating of 300 watts. How many volts does it need?
To find the voltage required for the flat-screen television, you can use the formula: Power (watts) = Voltage (volts) x Current (amps). Rearranging the formula gives you Voltage = Power / Current. Therefore, with a power rating of 300 watts and a current of 3 amps, the voltage needed is 300 watts / 3 amps = 100 volts.

How many amps are required to run a tv DVD player and a tivo box?
To determine the amps required to run a TV, DVD player, and TiVo box, you need to know their wattage ratings. Generally, a standard TV might use 100-400 watts, a DVD player around 20-50 watts, and a TiVo box approximately 20-30 watts. Totaling these wattages gives you a combined usage of about 140-480 watts. To convert watts to amps, use the formula: Amps = Watts/Volts; assuming a standard voltage of 120V, you would need approximately 1.2 to 4 amps in total.
