A perfectly efficient machine, which doesn't exist in the natural world. The reason it doesn't exist is because any kind of work gives off energy byproducts (for instance, heat differential, friction, so on and so forth). Kind of like a perpetual motion device (which you could make by linking the outputs to the inputs on a perfectly efficient machine).

What does input volts and output volts mean?
The terminology would typically reference a device such as a power supply, charger, diverter or transformer. The Input Voltage is the voltage supplied to the device to make it work. The Output Voltage is what the device supplies to an application. For example, a power supply for a laptop might convert 120 VAC to a voltage like 19.5 volts (A Sony Laptop) for charging a laptop battery.
In a real machine why is the work output always less than the work input?
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
What is half wave precision rectifier?
A device that converts full wave signal to half wave rectified dc signal. The device operates only for half of the input cycle during which the input signal is alllowed to pass and stops transmission of the signal for other half cycle. ok?
What is the ratio of the energy a machine delivers to the energy supplied to it?
efficiencyThe ratio of useful energy to total input energy is called efficiency. It refers to the percentage of the work input that is converted to work output.
Formula for calculating efficiency of a power supply?
Efficiency = workout / workin * 100% how do I format this in the worksheet if the workout=KG what the work in will be?
What device works as an output and input device?
A Touchscreen Monitor will work as an input and output device
How does an output work?
how does input device work
What does an output device in an electrical circuit do?
how does input device work
Is USB drive an output or input?
It's a storage device... It is to store data,and use the data from it to let other input/output/processing devices work... do not get confused thinking it as a input or output device...
What is the difference between input nd output devices?
The difference is input programs information output tells you information
Is a touchpad a input or a output?
A touchpad is an input device. It operates on the same principle as your mouse does, taking your movements or gestures and translating them into a form the computer can understand in order to get work done.
All simple machines ideally work on the principle that?
ANSWER: work input equals work output
If the output work of a simple machine equals the input work the machine is said to have efficiency.?
In that case, the efficiency is said to be 1 - or equivalently, 100%.
Is harddisk an output device?
It's an input and an output device. Programs and data are input from the hard-drive to the computer's memory for processing. The results are written back onto the drive when you save your work.
Is webcam output or input device?
Input
Is a processor an input or output device?
Input in the sense that it helps process data/information around the system AFAP but output in the sense that the data/information is to the processor and they do the work from there.
How will the work done on the input piston compare to the work done by the output piston in a hydraulic device?
The work done is equal
