How many kilowatts does a TV use in a hour?

Answer 1

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.

Answer 2

The power consumption of a TV varies depending on the size and model. On average, a typical TV consumes between 80-250 watts of power. To calculate the kilowatt-hour (kWh) usage in an hour, you would divide the wattage by 1000.

Answer 3

Examine your television set; somewhere at the back, you should see how much watts it uses. If it doesn't, look for volts and ampères, and multiply those to get watts. A kilowatt is 1000 watts; a device that uses 1000 watts will use 1 kWh per hour; one that uses 100 watts will use 0.1 kWh per hour, etc.

Answer 4

Check the power rating of the TV, and multiply by how many hours you used it for. Say if it uses 180W and you have it on for 4 hours, you will have used 180W * 4 = 720 watt-hours which equals 0.72 kWh. This won't be exact, the TV will use different amounts of power depending on what is displayed on it, how bright the light it is emitting, how loud the speakers etc, but this should give a pretty good estimate.

Answer 5

"Average TV" is an ill-defined term. Any given TV should have its power requirements listed (probably somewhere on the back); they'll be given in watts (a power, or energy per time, unit) rather than kWh (an energy unit). Most likely it'll be somewhere between 100 and 400 watts, meaning that in an hour it will use between 0.1 and 0.4 kWh.
