If you look at your television set's nameplate, it will specify its power in watts. A watt is simply a joule per second. So, if your television is rated at, say, 300 W, then it is transferring energy at the rate of 300 joules per second.

What is transferd energy?
I assume you mean what it is converted to. It can be converted to many different types of energy; that's one of the things that makes electrical energy so useful. (The other useful feature is that it is relatively easy to transport.) For example, a heating device can convert electrical energy to heat; a speaker converts it to sound; a television set or a computer monitor converts it to light; etc.
What energy does TV use?
A TV uses electrical energy.
Why is electricity essential for both improving public health and modern communications?
Public health is improved by getting knowledge and information, to as large public audience as possible. This is achieved by better communications. Modern communication relies on TV, radio, internet and telephone, all of which is reliant on electronics, which is driven by electricity. Non-electric forms of communication such a semaphore, smoke signals, mail and verbal, just do not compare with modern communication, for getting the message 'out there'.
What is the total energy used if an average person uses a tv computer refrigerator toaster light bulbs fan air conditioner space heater hair dryer Xbox Wii oven stove and a micowave?
TV 150 watts, computer 200 watts, laptop 40 watts, refrigerator 15 watts average, toaster 900 watts, light bulbs 15-150 watts, fan 20 watts, a/c 3000 watts, space heater 2000 watts, hair dryer 1000 watts, oven/stove 3000 watts, microwave 1000 watts. Total energy used is equal to the watts times the time. The total energy in units or kWh is the power in kilowatts times the time in hours.
What do nuclear power companies do?
They generate electrical energy from nuclear energy, and then distribute it through wires to your house, where it can be used to run your lights, your TV, and your electric can-opener.
How many watts does an avrege tv use in a half hour?
The average LCD T.V. uses 350W. This meets ENERGY STAR requirements. The average plasma TV uses over 1000watts. In any case, the question doesn't make sense. Watts is a measure of energy flow NOT an amount of energy. In half an hour a 350w TV uses 630,000 joules of energy. A 750watt TV, or any other 750w appliance, uses the same amount of energy in a quarter of an hour. 350watts means 350 joules per second and it makes no sense to say 350watts/second/halfhour. It is a 350w applicance whether it runs for half and hour or a week. It is always 350watts.
How does a TV transfer energy by heating?
by electricity
What are useful and non-useful energy transfers for wind?
Example: TV. Electricity- Heat, light, sound. Useful energy transfers would be electricity- light, sound because that's what your TV actually needs, but electricity- heat would be wasted energy or a non-useful energy transfer because your TV does not need to produce heat, unless of course you can't afford central heating, but then isn't heating more important than a TV???? Summary: Useful energy transfer: The purpose of the object is fufilled by this transfer. Non-useful energy transfer: The purpose of the object is not fufilled by this transfer, and in effect, this transfer is a "side effect" of the useful energy transfer. These transfers waste energy.
How does electrical energy transfer through electric circuits generators transformers and power grids before it gets to your tv?
from negative to positive
What is The transfer of energy in invisible waves?
When you use a microwave heat is generated by the friction of molecules within the food bouncing off one another. Radiant energy is sunshine waves of light.
What are the world's energy needs?
Among other things, humans need energy:* For food* For transportation* For lights* For heating* For operating diverse devices, such as computers, television, microwave ovens, kitchen stoves, etc.According to the Wikipedia article on World energy usage, "The IEA estimated that in 2012 the world energy consumption was ... 5.6 × 10 to the power 20 joules".
Is HD TV the best TV for energy saving What about Plazma, are they energy drainers?
Most, if not all, HDTV's are made to use as little energy as possible. Most will have a display setting with low back-lighting to save even more energy. And of course, the bigger the screen, the more energy it consumes. It looks that the average plasma TV uses more energy than an LCD or LED TV of the same size. http://reviews.cnet.com/green-tech/tv-consumption-chart/
What is the energy transfer for a television?
Electrical to sound+light+heat
What is the typical energy consumption cost of this TV?
The power consumption of this TV is 5 amps. It uses around 822 kilowatt hours a year average use.
What are three things that transfer energy through heating or light?
Trick question: all 3 of them are right Colin hits a drum, causing the small bones in his friend's ear to vibrate. An opera singer sings a high-pitched note, causing a glass to break. A loud clap of thunder causes a window to vibrate.
What types of thermal energy are responsible for tranferring heat from oven to brownies?
In a conventional oven it's mostly conduction,with a bit of air convection thrown in.There are "ovens" (as seen on TV ... mostly at 3AM) that use hot air and forced convection as the main heat transfer technique.
