How might you convert the generator in (http://www.aerospaceweb.org/question/propulsion/jet/generator.jpg) so that instead of producing alternating emf and current it will produce direct current? Would it be a steady D.C? Sketch a graph to show how the emf would vary with time.
The Attempt at a Solution
I drew something like this. In other words, I assumed that you just change the slop rings into a commutator.
I don't know about whether or not it'd be steady D.C.
As for the graph I think it's just a sinusoidal graph?
