For those that passed, to what do you attribute your success?? - I would say 3 major things: PRAYER, practice exams (get a good practice test, block out an 8-hour day and simulate the real test.), and strategic approach to TAKING the test. a. I read all the way through the test and marked...

Good Morning....I would like to see how you would solve this problem. There were a couple of steps in the solution that disturbed me like dividing the reactance of the rotor by .4(slip) and the appearance of 6.97 in the calculation for I(l). Here is the problem: A six pole, three-phase, wye...

Can anyone give me some guidelines/basic assumptions to keep losses straight when dealing with AC and DC machines? Is power to the shaft the same thing as P(out)? Is it true that P(air gap) is equal to P(rotor) only for synchronous machines? When I solve machine problems, I am not confident...

It's amazing the effect intense studying has on your brain. Now I am tripping up on something which I'm sure is very simple - the equation for apparent power. S=VI* or S=VICos(theta) or S=sqrt(3)VICos(theta) How do I know when to use which equation? Thanks....Sharon :tardbang:

Would some brave soul like to give me the basics when it comes to Electric Machines? I am not a Power Engineer but am taking the Power PE for the second time. I have a real mental block when it comes to the machines problems. I am using the EERM by Camara and working through those problems...
