What is the useful output energy of a table fan?
The useful output energy of a table fan is in the form of mechanical energy, which is used to create airflow and cool the surrounding environment. This mechanical energy is generated by the fan blades rotating and pushing air in a specific direction.
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.
Why a fan spinning have energy?
A fan spinning has energy because it is converting electrical energy from the power source into kinetic energy which is responsible for the movement of the fan blades. This kinetic energy is what generates the airflow that the fan produces.
What kind of energy does a fan represent?
A fan represents mechanical energy, which is the energy associated with the movement of an object. The motor in the fan converts electrical energy into mechanical energy to rotate the blades and create airflow.
How is energy stored in a electric fan?
Energy in an electric fan is stored in the form of electrical energy in the batteries or power source that powers the fan. When the fan is turned on, this electrical energy is converted into kinetic energy, which is the energy of motion that powers the fan blades to rotate and create airflow.

What is the useful energy output and wasteful energy output of electric fan?
The useful energy output of an electric fan is the kinetic energy produced by the movement of air, which provides a cooling effect. The wasteful energy output includes heat generated by the fan's motor and other components, which is not utilized for cooling. Typically, a significant portion of the input energy is converted into heat, making the efficiency of electric fans relatively low compared to other appliances.
What is the energy that is not useful called?

Useful and non-useful energy transfers for coal?
Useful: Energy Light Sound Non-Useful: Electricity C02
Why don't we convert mechanical energy of fan into electrical energy using dynamo?
A fan needs energy to work. Suppose we use a dynamo, driven by the fan. The output of the dynamo is supposed to drive the fan. In this loop, some energy leaks away, into moving air not captured by the arrangement set up to drive the dynamo. More energy is lost in the working of the fan, and of the dynamo, appearing as heat and wear. If we provide this system with 100 joules to start it off, soon all that energy will have leaked away and pretty quickly the thing will stop working. On the other hand, if your fan is a windmill driven by external sources (wind), then the wind energy can be converted to useful energy. But not to drive the windmill.
What energy is stored by a mini fan?
The fan itself stores no energy. If the fan has batteries these sore chemical energy.
Why a fan spinning have energy?
A fan spinning has energy because it is converting electrical energy from the power source into kinetic energy which is responsible for the movement of the fan blades. This kinetic energy is what generates the airflow that the fan produces.

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
How is energy stored in a electric fan?
Energy in an electric fan is stored in the form of electrical energy in the batteries or power source that powers the fan. When the fan is turned on, this electrical energy is converted into kinetic energy, which is the energy of motion that powers the fan blades to rotate and create airflow.
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.
