I was talking to my physics teacher today about electric motors and used some information I learned here. I'm not calling you guys wrong by any means, I just would like to know what is real. He claimed two things: 1. As load on an electric motor goes up, current goes down (I know this is wrong but he wouldn't provide any proof) As I was trying to explain this to him, I started talking about how an electric motor generates electricity, as it spins, making the potential difference across the coils lower, and according to ohm's law, reducing current. According to him, electric motors do not generate any electrical energy, I again can't see this as true because of the law of conservation of energy. Some of the energy is used to accelerate the motor, but after that, the only energy actually being used is turned into thermal from the friction of the bearings (assuming no load). So can anyone explain what he was on about?
