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 type of energy transfer does grilling a hamburger use?
It goes from chemical to kinetic.
What is useful energy transfer when coal is burnt?
Chemical energy is transferred to electrical energy! :) :p
What is the useful energy transfer in a wind turbine and generator?
Kinetic energy is transferred to electrical energy.
What is the energy transform that happens in the generator?
The generators transfer mechanical energy into very useful electrical energy.
What is the useful energy transfer when coal is burnt?
Chemical energy is transferred to electrical energy! :) :p
Is heat released from every transfer?
Energy always turns from useful energy to less useful forms of energy. so in theory the answer is no, but in reality there is always some heat generated in all transformations.
What is the energy transfer in a light in the ceiling?
it is electrical to radiant and thermal I'm not sure about that answer i think it's electrical to light (useful energy) and thermal (which is the wasted energy)
Why electricity is useful?
What makes electricity useful is that it is relatively easy to (a) transfer it over large distances, and (b) convert back and forth with other forms of energy.
Why is a transfer useful in an amplifier?
Transfer means to allow through (science-transmit e.g a window and light energy. the light energy is transmitted through) and so if the energy wasnt allowed through there wouldnt be a current or circuit because the energy would be lost i the amplifier
Is the transfer of energy called?
The transfer of energy is called Energy Transfer
Can some energy is lost during every transfer or conversion.?
Usually some energy is wasted, yes. Energy is not "lost" in the sense of conservation of energy; energy is always conserved. However, useful energy gets converted into unusable energy all the time.
