All right, I was just wandering about something. First, when we have a electric generator, than the rotor in it will rotate easily until current is drawn from it, correct? In other words, counter torque won't be produced until current is drawn. If this isn't true, than just stop reading the rest of this post, because it won't make much sense (I read this about generators in my physics book, but i don't quite understand it. Anyone?)
OK, so now let's attach a metal plate to the positive and negative end of the generator so that each plate is charged to a respective voltage. Take a large strip of conductive metal, and place the strip underneath the positive and negative ends so that a positive charge is electrostatically induced on one end of the strip and a negative charge on the other. Due to this, will not a large current form that goes from the positive to the negative end of the strip of metal (the negative end of the strip is connected to a chassis ground)?
So here's the question. Assuming no current flows from the positive and negative induction plate, which is connected to the generator, will this not reduce significantly the counter torque of the generator rotor? You're still getting power, but no current is flowing from the generator. I remember reading in my physics book that only when current is drawn from the generator is a significant counter torque induced in the rotor.
Any thoughts? I probably left out something that i didn't consider but that's why I'm asking! :yuck:Thanks in advance!
