thanks so much to everybody that added their thots, this was totally helpful. raised more questions but is a good catalyst for getting back to my old books. you probably think i havent studied any of this before but, embarrassed to say that i have, and forgot a lot of it or maybe thot i knew it but apparently misunderstood, but was able to get enuf right on tests to get thru
in the field you're busy working and figuring out ways to save time & cut corners & stay up with the [pardon me frinch] freeking codes, not much time to think
not rocket science, but anyway these concepts were very helpful to get straight: the inductive "magnetic field" coupling between transformer primaries to secondaries vs. the "electric field" capacitive coupling
[line charging] of something like long GFCI circuits that could make enuf current to trip them if their settings were too low.
and this from another thread, seeing that the electrons are trying to return to their source instead of the earth [really just another big conductor]. i think when i re-read my books these ideas will put it a new perspective.
kind of a last thing that might help is examples if anyone has any that might bring this back down to a "working in the field" level, like scotts Line Charging [Capacitive Coupling] GFCI example, or george's motor not stopping, [sorry but the Caesars Ghost thing must have been from years B.C.indy, didnt help], & paul's switch loop.
when you wire a fluorescent ballast, its just wiring to the ballast, where is the power factor correction capacitor that adjusts for the phase difference in the current and voltage?
there's a capacitor in a control box mounted in a pump house for submersible pumps, what is that doing? starting circuit vs. running circuit, right? sorry, thot i was thru asking questions
any other capacitors i should be familiar with that i probably work with regularly? and why they're used?
