DaveE replied to the thread 3-terminal device external modeling.You can't really describe a network without seeing what's inside of it. For a passive LTI network you should be able, with source... -
DaveE replied to the thread 3-terminal device external modeling.I think the only thing you can say for the most general case is that the terminal currents all sum to zero (KCL) and that there are two...

This is only correct if you view ##\Delta L## and ##\Delta B## as fixed numbers. In a setting where you have estimated errors, it is...
-
Agreed. When rounding off to the so-called appropriate number of sig figs what you are really saying is "Don't worry about the...
-
DaveE replied to the thread Errors and significant figures.When I was a practicing EE, none of this ever made sense to me. These problems rarely mention the probability distribution of the data...

DaveE reacted to FactChecker's post in the thread Finding the nth roots of a complex number with
Like.
By the time one takes complex analysis, he should be comfortable leaving it as ##\sqrt 2##. Leave the approximation accuracy for the... -
Why not heat a stainless steel water container, that is fixed-in-place? If heated from below, the water will circulate and mix, so ice...

DaveE reacted to Frabjous's post in the thread Other Which branch of engineering is more physics heavy? with Like.
It is too hard to say without knowing at what level the courses are taught and what is offered in the physics department. This is what...
-
DaveE replied to the thread Other Which branch of engineering is more physics heavy?.But you asked about the convergence of engineering and physics. Engineering is nearly always about devices. Otherwise you'll be stuck...

Einstein was in academia. He published in the professional scientific literature of his time. He was an academic that also worked as a...

DaveE replied to the thread When 50,000 volts go through a wire at 5,000,000 FPS - The Slow Mo Guy.Yes, that works for me. But the charges inside the wire (the waveguide part) are also involved. Ultimately it's a bit too complex to be...

DaveE reacted to tech99's post in the thread When 50,000 volts go through a wire at 5,000,000 FPS - The Slow Mo Guy with Like.
5 M frames per sec is not fast enough to capture the wave that travels down the wire starting from the switch, which takes just about a...

DaveE replied to the thread Converting PSD into equivalent sound pressure for an underwater hydrophone.If you have a narrow resolution bandwidth you can use that to convert the spectral density into a voltage. You can assume the psd is...

DaveE replied to the thread Other Which branch of engineering is more physics heavy?.Lasers. Quantum Computing. Semiconductors.

DaveE reacted to russ_watters's post in the thread How do people explore new ideas in physics? with Like.
It's not a "holier than thou attitude", it's a true reality. That's not what I said. I said "near zero". It's certainly possible (not...
