DaveE reacted to sophiecentaur's post in the thread Why does the amperage go real high if there is a low voltage short? with
Like.
Not many five years olds would understand even the most basic of EE and your theoretical five year old might, hopefully grow up to have... -
DaveE replied to the thread B Six Pencil Puzzle.Yep. Stuck on the tile though. I don't know if I should do it myself or pay someone. Apparently thinking about it harder doesn't...
-
DaveE replied to the thread Voltmeter readings for this circuit with switches.Yes, that makes sense. It's not standard nomenclature, but the alternative is ridiculous. But then they shouldn't have values attached...
-
DaveE replied to the thread Severe Turbulence for Delta Flight 56 (NTSB report).More like 1,000 ft in 20 seconds, I think. The truth is out there...
-
DaveE replied to the thread Voltmeter readings for this circuit with switches.BTW, in the language of schematics, this smells like AI generated. I've never known a human EE that would create this. As Pauli is...

DaveE replied to the thread Voltmeter readings for this circuit with switches.Sorry to be blunt, but this problem is nonsensical. There are a few things you should never see in an idealized circuit schematic. 1) A...

DaveE reacted to Baluncore's post in the thread How might electronics be different if AC voltage was 72V at 45 Hz? with Like.
This thread is about low frequency, low voltage supply, not the game theory of ELINT and IFF etc.

DaveE reacted to jrmichler's post in the thread I need a concave mirror with a focal length of 150 feet with Like.
I calculated the sun image diameter assuming: Sun 865,000 miles diameter Sun 93,000,000 miles distant Focal length 150 feet Perfect...

DaveE reacted to .Scott's post in the thread Who is responsible for the software when AI takes over programming? with Like.
The same people who were responsible before the AI "took over". If someone does their home work with AI assistance, it is still their...

DaveE replied to the thread Share Animal Pictures: For Animal Lovers.In these troubled times it wouldn't hurt to spend more time playing with your dog. It works for me anyway.

This sea slug (like many corals) can use algae they have incorporated into their skin to photosynthesize.

DaveE reacted to tech99's post in the thread I Do electron density waves accompany EM waves in coaxial cables? with Like.
I think so. I believe the wave has the same propagation constants and Zo as the TEM wave, so you don't notice it. It is of small...

DaveE replied to the thread I Do electron density waves accompany EM waves in coaxial cables?.The velocity must match that of the EM wave which is ##\frac{1}{\sqrt{\epsilon \mu}}##. If your derivation doesn't produce that then I...

DaveE reacted to sophiecentaur's post in the thread What is the difference between a switch leg and a hot leg? with Like.
A trucker in a cafe may not be the best source of this kind of information. Even nice blokes can talk BS about EE. There's a principle...

DaveE replied to the thread I need a concave mirror with a focal length of 150 feet.Great! What happened to the tree then?
