There are a number of reasons why machines cannot convert all of their input into useful work. This is because they were made by humans and have a margin of error.

Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent). Efficiency = Useful Work Output ÷ Work Input
Losses of energy within the machine- some of the energy is used up by friction, and converted to heat. There is also the matter of efficency of a machine. The less efficent, the more power you must put in to get the same output.
The output work from a machine cannot be greater than the input work because of the law of conservation of energy. Energy cannot be created or destroyed, only transformed from one form to another. Therefore, the output work of a machine cannot exceed the input work that was initially put into it.
You can.
no you cant
you cant
The transformer needs AC at its input. The battery provides DC.
machine cant generate power where as engieen can
sorry but you cant make a time machine. it is impossible.
u cant
no you cant
