I spent a whole semester learning P I E and the algebraic formulas for resistance, impedance, power, watts, reactance, induction, etc.... Over and over. Don't remember any of it because I've never had to use it as a wireman. Besides studying for licenses. Cool theories.
NICE VIDEO Mike, ...make sure your students know effects of 'power factor' (is this in another video?) Some things only work for purely resistive loads....which homes are NOT. THANKS MUCH!!! ps I remember seeing a small 'generator test-truck'. It was loaded with a huge resistor-bank to rate portable generators....big surprise when the generators didn't work to 'proven spec' when running at home!
Mike Holt are you safe we hear there is a massive hurrican called Helene. People lost their homes and are evacuating. I hope your safe it started September 30. Be safe Mike! Im from California!
