revision of whats useful 2

[bigheadted]

its a few years since i finished college and ive been doing mundane work since so ive forgotten a lot of the formulae etc that i learnt about at the time.
can anyone recomend a web site that might give me a little refresher on electrical power calculations especially drives and motor control. (up to a hnc level) just to save me showing my self up in my new job im sure when i start reading it will all come back
thanks

Have you checked out a good 'ol Schaum's outline for Electrical Engineering?
