For the illiteratti among us, please explain the concept behind the 12 inch pigtails a bit more. My takeaway from the article was that 12 inches of wire act as a "resistor" in series with the pin. Would you not need to tailor each pigtail to attain the correct resistance? Or, just by having this increased resistance, within a range, does it drive the pins to share current? |
Correct. And thank you for that question. I should
have described that effect in the article. I've edited
it to include that explanation.
Quote: | The final takeaway was that, without the pigtails, one pin would hog the load, overload and fail, causing a cascade failure of the entire connector under load. Yes, no or should I go back to my corner? |
Not at all . . . in fact, you've spotlighted
the need for further elaboration.
