I have been know to teach an electrical math class or so at the local college, My original degree is Electronics engineering technology and I have covered the whole spectrum from circuit board level repairs on sophisticated electronic equipment for our U.S. Military to clipping in 75 Kv transmission 100 feet up on a pair of gaffs.
Volts, Amps, Ohms, Henry's, Hertz, farads are all the same on little circuit boards or power lines only the units change.
But here is the deal, If you need any math help on electrical theory feel free to contact me here or by PM and I will give you all I know.
