Current flow in a generator?? In an AC generator what are 2 things that are going to determine the current flow (or the direction of I)?

Question about computing torque?? When computing torque of a electic motor I use the formula T=IAB, where as I represents the current, A represents the area, and B represents the magnetic field. My question is, what is the meaning of the product of IA?

Utility companies AC instead of DC?? Why do utility companies transmit electric power via AC instead of DC?

Thank you, I did forget to do that.

I am still lost. Can anyone explain it on a more elementary level? I've been at this for about 10 hours and my brain is fried. I checked the book but it isn't telling me much.

Ok, based on what you are telling me I came up with: How much potential energy (joule) has it given up? = 107.8 J What is the power (watt) output? = 26.95 W If that power output was kept up for 24 hours how many kWhr of energy would be produced? = 646.8 kWh Am I doing it correctly?

If anyone could help me with my homework I would GREATLY appreciate it. I am totally lost. There are 2 questions. If you could tell me what/how to do it, I'd be happy to do it. I just need to know how. Thanks so much Here is question 2: A 5.5 kg mass is dropped at a constant velocity...
