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?
The use ful energy from headphones would be sound , the wasteful would be battery power.
What is electrical energy transferred 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.
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 transfer for a television?
Electrical to sound+light+heat
What are examples of useful energy?
tv light bulb

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

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.

If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out is light energy. Heat energy is also produced but is not useful
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.
Useful and non-useful energy transfers for coal?
