I need help with Generators.
I know the difference between the two, DC using a commutator and AC using slip rings, but I have a few questions.
1. The commutator reverses the current every half revolution so the motor keeps turning in a DC, but what do the slip rings do for AC? (I am confused because the graph that you would expect is where the EMF fluctuates between zero and a maximum as if flows in one direction, but the graph for the AC varies like the sine wave? I am very confused.)
2. How do both the DC generator and the AC generator work? I know something about the current being produced differently, but other than that I am confused too.
3. If a DC motor gets current supplied from the terminals, which makes the coil spin, how does a generator work? I dont understand because the coil in the generator turns aswell? And I dont understand how it can turn if there is no current produced?
SORRY FOR THE LONG WINDED QUESTIONS, but my exam is on thursday = ( Is there any way anyone can explain this to me in simple terms?
