    Magnetic lift

    Hello, I have an idea i have been working on for some time. I am a meteorologist and pilot, and i love aviation, especially design. I have been playing with the idea of magnetic lift (as in when one magnet is repelled from another magnet) or electromagnetism in an engine, to create a different...

    Alternators and how they supply current

    Hello, My question is how do Alternators(Like a cars alternator) supply current? Do they act like a current supply or do they act like a voltage supply that can have current drawn up to its rated value? If I have stepper motors being powered from it would they draw the right amount of current...

    Integral of Unit step function

    This isn't really so much of a specific example from a textbook, I just need to understand how to do this kind of integral and from that I can infer how to do all of the other problems. 1. Homework Statement The current problem i'm having trouble with is: Integral of (5u(t-1)) from T to -T...
