I really want to know 1 HP engine can make how much electricity using a generator.

theoretically 746watts. however if the efficiency is 'x' per cent then 7.46x watts

746 watts is the nominal value IF:
There are no losses in friction and electrical resistance,
and the engine cannot be overloaded.
Most engines will tolerate overload for some period of time, and efficiency is never 100%, So your answer has to entail assumptions,which you have not supplied.

1HP= 746 watts
But depending upon the efficiency of the engine we get less than this value.According to carnot's cycle we can never achieve 1004 efficiency.

Let's assume your generator is 80% efficient:
.80x.75kw = .6 kw or 600 watts

not many because the more power you use the more power it takes to turn the generator

Do the math. Ohm's law applies here.

less watts then it takes the motor to run
