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?
Useful: Energy Light Sound Non-Useful: Electricity C02
A comparison of amount of energy before a conversion with the amount of useful energy after a conversion?
Usually, the amount of useful energy after a conversion will be less than the original energy. In no case can it be more.Usually, the amount of useful energy after a conversion will be less than the original energy.

What we energy that is not useful?
Waste energy
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out of a light bulb is primarily in the form of light and heat. The electrical energy is converted into light energy that illuminates the surroundings and heat energy that warms up the light bulb and its surroundings.
Can energy be destroyed but not created?
Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.
If you have a device that has an energy efficiency of 0.7 and you put in 150 units of energy how many units of useful energy will you get out of it?
To calculate the useful energy output, multiply the input energy by the energy efficiency. In this case, with an energy efficiency of 0.7 and an input of 150 units, the useful energy output would be 0.7 × 150 = 105 units. Therefore, you would get 105 units of useful energy from the device.
Is gold useful in energy production?
Currently, gold is not useful in any form of energy production.
What W is the energy that is not useful?
Waste energy.
What is the name of the amount of useful energy you get from a system?
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
How can you calculate the efficiency of an appliance in terms of power?
vague question. Efficiency in terms of energy = useful energy/total energy x 100 vague question. Efficiency in terms of energy = useful energy/total energy x 100
Total energy input equals equals the useful energy output plus?
Efficiency = ( useful energy output / total energy input ) x 100
