Actually, I'm kind of curious how there is \$i_0\ne 0\$ when the switch above it is open for all that time while \$t\lt 0\$. No place for it to go while its switch has been in its indicated position...

@internet You don't want to give us the wiring/drawing file. That's for display purposes. The netlist tells us what Spice sees. Please add the netlist to wiring/drawing file. Is the load, Z2, supposed...

If you are missing two of the three, and only have the one equation, then you are stuck. Do you have a graph of some kind to add to the mix? Or some other equation you didn't mention?

Just skimming, it sounds to me that you want a single boost switcher design that you can easily modify (or use a potentiometer and a meter to calibrate it) that will provide output voltages in the...

You don't provide details about circuitry. But I'm not sure if it helps. It might. But taking into account that many of these look fine and fast and taking into account that some of them look very much...

I'd recommend reading this EESE post closely. It may cover some part of what you want.

Cute. I just did the same thing and got this which is just slightly different. I wonder if we are using different versions. I'm using the x64 version called 17.1.5.

Axodarap, I second @Andyaka 's comment. Context matters and a single copy of a single behavioral diagram doesn't quite cut it. Also, don't worry about language differences. We can ferret that out with...

View ArticleComment by periblepsis on Find the equivalent resistance between \$A\$ and \$B\$
@MathStackexchangeIsNotSoBad Mattman944 has practically given the whole thing away to you. Suppose some points have the same voltage. V1 for example. Suppose you now take a wire and connect those...

Yeah. Shift the sine to a cosine by subtracting 90 degrees (pi/2) for the ii case.

I can't speak to Keil uVision. It's been many years since I used Keil. But I can talk, generally.An assembler usually produces an object file. This is a custom formatted file that typically is composed...

I'm a little confused about your writing this: \$0 - 0.4261 = -0.4216\$. The truth is \$0 - 0.4261 \ne -0.4216\$. I must be misreading you.

@David777 No one else can, either. It should have been written as 11100.10000 in 5.5 format.

@Ayush Yes, that's the meaning of a phasor. It's just the fixed-length vector \$A\$, as rotated by the fixed angle \$\phi\$, at \$t=0\$. Also, since \$s=\sigma+j\,\omega\$, your last expression is the...

Math, That looks not so unlike your cube problem, earlier, once it has been simplified. It has a not-dissimilar symmetry, too. (The bottom three resistors are a mirror image of the top three.)But the...
