Wow is right.
I fully understand why you would want to pull yourself out from a hot potato.
Thanks for the warning. Duly noted.

I doubt that very much.  That you think you do understand is only more cause for concern

Your very welcome.

Consider getting a low voltage center tapped transformer to work with.  Something like a 25.2 volt CT transformer, a couple 12VAC pilot lamps, and a few resistors will allow you to safely perform similar AC measurements.

Great advice PW.  I have always been concerned about people playing with mains power or with very high voltages.  There is no real reason to do so.  Plus I believe your forearm muscles can contract if you pick up a live wire such that you can't let go and you can get electrocuted.  I saw a nasty clip once where someone stepped off of an electrified bus.  Some power lines had fallen onto the roof of the bus.  For one moment one foot was on the bus stair and the other foot was on the ground and in an instant they were dead.

And there is the justification for me asking you the question that you couldn't answer about the circuit that consisted of a voltage source and one single component, a coil.  You talk the big talk like "pull yourself out from a hot potato" but you clearly still haven't mastered the basics of an Electronics 001 course.  And look at EMJunkie, he still "talks the big talk" almost every day, and he also was incapable of answering the same question.  Both of you were completely lost for a very basic question, so how can you possibly investigate supposedly advanced concepts?

And if I dug it up earlier in this thread, you would find Brad getting hot under the collar with the discussion about resonance and willingly accepting taking on the question about the wine glass and resonance.  And in the end the same thing happened with Brad.  Why was that brought up?  Because supposedly the team was going to investigate a "resonant Joule Thief" so why not be straight on what resonance really is?  And clearly the "resonant Joule Thief" is dead and the guru Smoky2 has vanished in a puff of smoke.  If you look at a lot of his early statements about resonance they are complete nonsense.

Why am I bringing this up?  I suppose it's because of the insane "Earth is a pizza pie and we are all just Mants" thread.  Frustration.  Meanwhile the FBI has an arrest warrant out on John Rohner.

micro low i get this feeling that you are getting ignored and that is bad for you, because YOU NOBODY UNLESS SOMEBODY MAKES YOU SOMEBODY.and mirom who is this john rohner
