[sdiy] OT: Generator?

[Mitchell Hudson]

    I got in an argument with a guy the other day about genertors. He
says that if you are turning the crank on your generator and there is NO
load connected to it it will get harder to turn when you connect a load
to it. For example you have a generator connected to a radio the radio
is off and you are turning the crank; you turn the radio on and it takes
mre force to turn the handle.
    After talking with a few people I was convinced that this was true
but no one could explain it.
