How do you calculate the power output of a generator. I know that P = I x E and that you can know the output voltage but how do you calculate the current in order to determine the power output?

Can someone please tell/explain to me how voltage affects electrons. Does it determine the speed of the electrons in a conductor? Is so why a power supply rated 12v 3A and another rated 9v 3A have the same amount of electrons traveling at the same speed through the conductor. My big question is...
