100 % efficiency,
and the beginning of perpetual motion.
OR you have an electric heater - and all loses are what you want.
The machine would have 100% efficiency if the input work is equal to its output. This means that all the input energy is fully converted into useful output energy without any loss.
In an ideal scenario where no energy is lost as heat or through friction, work input should equal work output according to the principle of conservation of energy. However, in real-world situations, some energy is typically lost as heat or sound, leading to a slight discrepancy between work input and output.
If the useful energy output of a system is equal to the energy input, the following calculation can be done:Efficiency = (Useful energy out) / (Energy In)Efficiency = 1Efficiency = 100%Therefore, the machine you describe does have an efficiency value, which is equal to 100%. Very few situations like this exist though, unfortunately.
The total energy output of a hairdryer must equal the total energy input due to the law of conservation of energy. According to this law, energy cannot be created or destroyed, only converted from one form to another. In the case of a hairdryer, the electrical energy input is converted into heat and kinetic energy to dry and style hair, meaning the total energy output must match the energy input.
In theory, the work output can equal the input in isolated systems where there are no energy losses. However, in the real world, energy is often lost to factors like friction, heat, and sound, so the work output is typically less than the input. This is explained by the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed.
In theory, work output might be equal to work input; that would be 100% efficiency. In practice, the output of a machine will be less than the input; i.e., some energy will be lost.In theory, work output might be equal to work input; that would be 100% efficiency.

The result (ratio) of such a comparison is called the efficiency. Note that total energy output must be equal to energy input (conservation of energy); however, what is relevant for this comparison is the useful energy output.
The machine would have 100% efficiency if the input work is equal to its output. This means that all the input energy is fully converted into useful output energy without any loss.
Then you can say the device has a 100% efficiency.
The first law of thermodynamics requires that the energy input to a system must equal the energy output from a system plus the accumulation of energy in a system. If no energy is accumulating then the energy input is the heat in and the energy output is the work and heat out.
According to the law of conservation of energy, energy cannot be created or destroyed, only transferred or transformed. This principle applies to work input and output, as the total work output of a system will always be equal to the total work input. Any work done on a system is transformed into some form of energy that is then used to perform the work output.
In an ideal scenario where no energy is lost as heat or through friction, work input should equal work output according to the principle of conservation of energy. However, in real-world situations, some energy is typically lost as heat or sound, leading to a slight discrepancy between work input and output.
If the useful energy output of a system is equal to the energy input, the following calculation can be done:Efficiency = (Useful energy out) / (Energy In)Efficiency = 1Efficiency = 100%Therefore, the machine you describe does have an efficiency value, which is equal to 100%.

In a closed system, energy input is equal to energy output based on the law of conservation of energy. However, in practical systems, there may be losses due to inefficiencies, such as friction or heat dissipation, resulting in energy output being less than energy input.
The output work would equal the input work in a machine if there are no energy losses due to factors such as friction, heat, or sound. This means that all the input energy is effectively converted into useful output energy without any wastage. In ideal circumstances, such as in theory or in simplified mechanical systems without external factors, the input work should equal the output work.
