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.
Does a TV produce thermal energy?
Yes, a TV set produces thermal energy by converting electrical energy with the use of resistance.
What converts electirc energy to light and sound energy?
-- a lightning bolt -- a TV set
What is the energy transfer for a television?
Electrical to sound+light+heat
What kind of energy is involved in turning on a TV set?
To turn it on you use mechanical energy produced in the muscles in your hand. To energise the TV you use electrical energy
How does a TV transfer energy by heating?
by electricity
What is the average energy transfer of a TV in joules?
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.

When you turn on a television set what do you change?
Mechanical energy into electrical energy
How does energy help into television?
A device such as a television set won't work at all without energy.
Does a TV produce thermal energy?
Yes, a TV set produces thermal energy by converting electrical energy with the use of resistance.
Why tv produced electrical energy?
It doesn't. If you mean the TV set at your home, it USES electrical energy.

Do television store or use energy?
A television set doesn't store any significant amount of energy. It does use energy, to do what it's supposed to do.
What is the energy transfer for a television?
Electrical to sound+light+heat
How can eletricity be transformed into heatlight and sound energy?
That happens in a TV set.
What kind of energy is involved in turning on a TV set?
To turn it on you use mechanical energy produced in the muscles in your hand. To energise the TV you use electrical energy
