How many KWh per day = 120V & 110W?

This is about the KWh hours to run a LCD TV . How many KWh does the TV use when just plugged in...compared to when it is in use. Just the TV alone.

    The voltage does not matter in this case.

    Remember that 1 kWh is 1,000 watts consumed continuously for 1 hour.

    Different numbers of watts take more or less time to equal 1 kWh.

    Doing a little math should get you close for the operational power consumption.

    The power consumed when the TV is off is utterly inconsequential

    in comparison to what it draws when it is on.

    If you want a really close estimate of the energy consumed,

    get a "Kill-A-Watt" plug-in electric meter.

    You don't need the voltage. You only need that (and amps) to calculate the wattage.

    It would be 0.11KW/h, as 110W = 0.11KW and it's the power consumption in an hour.

    110W is the same as 0.11 kW. Run it for an hour and you've used 0.11 kWh.

    Assuming you are using it for the full 24 hours in a day that would be (0.11 kW)(24 h) = 2.64 kWh/ day. However it's unlikely you would have the set on for the full 24 hours.

    you did not mention the working hours ...

    i assume 8 hours a day ...so 110x8= 880 watt-hours or 880/1000=0.88 kilowatt-hours ....for a month it will be 0.88x30=26.4 kwh ...this will be added on your electricity bill ....

    Use an ammeter and measure current draw .

    There isn't enough info here. Consult the televisions manual. It should tell you what the power usage when idle is.

    2.64 KWh/day = 110W * ( kw/1000w) * (24 hr/day)

    That depends in part on the size of the television. I think LCDs are about 100 watts when in use. I will guess that it draws five watts when not turned on. So when it is running, it would run ten hours on one KWh.
