Spark Master,
Don't think for a second that you are alone in not understanding AC and Transformer Theory.
When I first got started as an Apprentice Electrician, it all seemed like Chinese to me.
The more I thought about it, the more it made sense.
Mind you, I didn't have ECN back then either.
You guys that knock a fella like SMF have forgotten what it is like to get back to the basics.
The basics are what matter to our trade.
Yet those that would knock a guy down for not knowing about theory, can't use simple tools like a Megger or explain why it should be used.
Just my 2c worth. [Linked Image]
