You turn the crank of a hand-held electric generator. The
generator spins a magnet inside a conducting coil in order to
produce an EMF which can power some load. In one instance you use
the generator to power a light-bulb with a small resistance, in
another instance you turn the handle while no load is attached
(an open circuit). In which situation is the handle harder to turn?
Explain your answer.
