Kiss my aura Dora right here on the floora.  - Frank Zappa

I'd kiss Frank's aura Dora anytime - if he were still alive.
Your aura Dora however is suitable only for wiping my floora.
Cheers

Regarding the question about which wave form was the correct one, I'll go out on a limb and say neither one, because I'm pretty sure you inverted CH2 (the current channel), and I did not see mention of this. Therefore the wave forms could not appear as they do with the probe orientation as depicted.

If CH2 was not inverted, the primary current would be lagging the secondary voltage.

Good on the wit, but your comment is still not true.

Really MH???  please show me where in stiffness the stiffness returns the system back to its original position or state.

No belief needed MH,, I know what I posted and I know you are incorrect.

So you do not want to worry about the exact term,,, why is it that when some other person uses the incorrect term you worry about it and go on and on until you get the term used that you think is correct?

Look MH,, you made an error and I am only pointing it out,, you may not like it but it is the truth.

Here is another for you

Now look at the antonym,,

http://www.dictionary.com/browse/antonym   just in case you do not know what an antonym is

Webby, there are technical and lay definitions for stiffness and elasticity.  I put up a technical definition for stiffness and I am sticking to it.  Can we stop this frivolous debate?  When terms are critical or not all depends on the context.  Duh.

You did not post correct answers.  If you believe you did please link to it and I will have another look.

How about stopping the bad boy routine with the antonym crack?

You are catching a cold from someone.

So, in a manner of speaking, in elecronics, resonance would be comparable to a battery or capacitor in that, you do not get out any more energy than was put into the system.  Would this be more or less correct?

I heard a guy on his youtube video "claim" that when he hits resonance in his circuit, that amps and volts go to infinity.  Now, I am not sure just how you could measure infinity amps or infinity volts...he was just using a DMM.

Resonance is a way of storing energy using AC.  It was a big fish claim.  The only reason you see amplitudes increasing with resonance is if some external source is providing energy, a la pushing a child on a swing.  Eventually the supplied power is equal to the burnt off power in the resonance.  i.e.; maximum resonant amplitude in an resonating electrical circuit typically means maximum power burn-off.
