The Truth About Power Cords and there "Real" Price to Performance

If you are going to be arrogant, pedantic, and rude, you better invest the time first to ensure you are not erroneous, ignorant, and misguided.


The voltage of the AC supply is a 60Hz sine wave. Your attempt at pedantictry is but a strawman. One has to wonder why you have to resort to a strawman as opposed to addressing the rest of my argument.Clearthink, would you like to try again, to show that you do not understand that the bandwidth of the power delivery to a linear power supply includes harmonics (typically odd harmonics), well above the primary frequency of the AC supply, i.e. there will be significant harmonics at 180, 300, 420, 540, etc. .... and that the sum of those harmonics will be significant, i.e. 30% of the primary is not unusual.


Further, would you like to illustrate how the typical linear power supply would operate if the only frequency of power delivery was 60Hz? I can wait. Why don't you draw it for yourself. Hint, if the only frequency of power delivery is 60Hz, then the current waveform must also be a nice perfect 60Hz sine wave.

audiozen:  Talking or debating with clearthink is like talking politics with the other party.  No one changes their mind but everybody ends up pissed off.  Clearthink clearly thinks there is always only one answer...his.  To debate with him (or Geoff) is pointless.

I understand that you’re feelings are hurt, that you’re ego is bruised, and that you’re self-image as an expert, authority, and arbiter of truth has been tarnished, damaged, and diminished and yet I congratulate you for stepping out of you’re "safe space" and venturing to where others can help you question, explore, and learn. Knowledge will come to you over time and I encourage you to continue you’re efforts.

I also encourage you to buy or acquire from you’re local library an introductory to basic electricity so that you can understand Ohm’s law and things like that, much of which is very simple! The complicated things come later but the best approach is to take one step at a time. Don’t give up you can do it! You are still very new hear to this group so time is on you’re side!

dynaquest4,


I had quickly come to one of those conclusions and I am rapidly reaching the other. This had started out respectfully with delkal, but unfortunately someone felt a need to "puff their chest". I don’t have any illusions they understand the topic or even care to. It is simply attention seeking. It is not an isolated event.


I do find it a bit weird they insist on repeatedly showing their ignorance about basic EE, even illustrating a knowledge level lower than a first year technician let alone a first year EE student. Oh well, I am only providing the space, they are shouting at the top of their lungs.

Their - possessive (they)
They're - contraction (they are)
There - position (here/there)

Here/hear?
