Comment by periblepsis on How is the reactance of a capacitor formulated?
@DPV Phasors are a stripped down simplification. I talk a little about it here. But the essence is that phasors remove the time-dependent part, leaving only the phasor (phase angle) part. Euler's is...

Gabriel, The title says you know \$v_2\$. So what is it? And how do you know?
View ArticleComment by periblepsis on What makes a MCU capable of higher temps than another?
The temperatures are relatively low, silicon-wise and may be due to non-volatile memory. I honestly don't know in this case -- will read answers. So can only guess from business considerations. They...

They provide the means (sometimes you can turn on only a weak low-side as well as a weak high-side) for these varying output driver configurations for a reason -- to make sure that they don't have to...

@hana Your terms are loose. I think when you write circuit, you mean only the cases that are fully connected (the nullspace of the transpose of the incidence matrix has exactly one vector that includes...

@SRobertJames I can show an approach pretty quickly, if all you are asking for is how to approach estimating the effects of raising Rc.

I don't know if you are shooting to write your own minimization algorithm or if this really is just for paperwork by hand. For paper, I use something like instead. I find it easier for 5- and 6-D. Past...

With enough current gain, and 2 prior transistors apparently is enough for the purpose, just consider Q1 as saturated. So the source voltage is applied across the series chain of R1, LED1 and BZ1. A...

Do not use Chat GPT for technical questions or much of anything else, to be honest. It lies. And does so, convincingly. And you can tell it that it is wrong and it will often admit it and then tell you...

I guessed IKF will cut beta to 400. And I forgot to add input attenuation of 1/(1+50/(7.912k|1978.772|400*1.3)) or down from 100% to about 89% before it gets into the bipolar. So...

@ch_7scal It's just three transistors. Why not provide the schematic? It's possible that some good advice could come from that.
