It uses electrical energy and produces sound
It uses electricity, in the form of volts and amperage, which equates to watts. It also receives the signal in the form of radio frequency which can contain analog or digital signals, and the newer TV's can also use the digital signal itself if it's equipped to do so.

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.
What is the useful and wasted energy in an electric heater a television an electric kettle headphones Thanks for your help?
In an electric heater, the useful energy is the heat generated for warming the room, while the wasted energy is the heat lost through the surroundings. In a television, the useful energy is the light and sound produced for viewing and listening, while wasted energy can come in the form of heat generated by the device. In an electric kettle, the useful energy is the heat used to boil water, while wasted energy can be heat lost through the kettle's exterior. In headphones, the useful energy is the sound produced for listening, while any energy lost through heat or vibration could be considered wasted.
What eventually happens to the useful energy transferred by a tv?
Some is used to drive the display, whether a CRT or LCD, and some is used to produce the audio signal, whilst some is used to power the circuits that decode the input signal. There is also some wasted energy from electronic parts that get warm, this is convected out of the grilles in the back.
What is the useful energy output from a TV?
The TV's electric efficiency depends on the type, size and brand of the Television. Typically a TV uses 80 to 400 Watts of electricity. Bigger Televisions use more energy than smaller ones. LCD's are more efficient than CRT's.
What is the energy transfer for a television?
Electrical to sound+light+heat
What are examples of useful energy?

What type of energy does a TV convert to?
Converts Electrical energy into the useful energy, light and sound. There will be some unwanted heat energy as well

What is energy transfered to?
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 transfers take place when you watch TV?
The main input energy is electrical energy from mains or power sockets; that energy is transferred to light energy for the pictures, and also there is sound energy (For audio), and all these energy are converted right back at heat energy as there is always a loss of energy in every device.

What is the energy transfer for a television?
Electrical to sound+light+heat
Why is electrical energy is useful?
electricity can be useful in alot of things. You will not imagine how much you use electricity throughout the day. You mostly use it for light. right now you are using electricity while you are reading this. You use it when your watching TV, or playing video games, or using an air conditioning machine. that is how electricity is useful.
What is the energy that is not useful called?
The energy that is not useful is called waste energy. It is the energy that is not harnessed or converted into a form that can be utilized for work or other useful purposes.
Useful and non-useful energy transfers for coal?
