Problem pH electrode buffer offset appears when solution is grounded. Detail I have a pH electrode in some conductive solution (~1000uS). The output (measurement electrode) is buffered by an el...
In my effort to clean-up and organize tags on EE.CD I arrived at a point where there are a lot of old tags with wrong capitalization. How should I request the staff to change them? Should I post ...
I have been watching this video and at 3:28 it says that a induction is inherently self-starting.Does this happen because of the energy stored and released in the windings of the statorFrom 3:41 u...
For my test bench I need an inductor (aka "reactor") that meets the requirements below. I have tried to purchase it outright as a made-up item, or the parts to make it (core and windings), but have...
I got my hands on a Tesla Model 3 aftermarket module (Display/Cluster) The IC's are labled with the brand 'PocketLink' Id like to know more about what these parts are. Chip1: PocketLink B2 003...
I always had trouble understanding the terms "digital" and "analog"; Wikipedia and various Q&A sessions didn't contain explanations I found clear. I understood that these terms aren't well defi...
I think your measurement instrument is fine. What is not is your understanding of resistance: there is nothing like this "resistance of water". In your case, the measured resistance depends on the...
One reason could be that N type MOSFET can switch loads that are in Drain, meaning that whatever the load voltage, you can turn it on/off directly with any microcontroller, provided that the MOSFET...
Currently there are $\boxed{\color{red}{\text{three}}}$ downvotes so maybe someone can explain why this has happened. Anyway, on to my downvoted answer: - You have "mentioned" the threat (the ESD ...
Let's take a look at the state of affairs for the past few weeks on this forum. For the past two weeks, some users has been posting a lot of questions, a lot of them self-answered. This is not a p...
You are asking about feedback in this circuit, and how R3 fits into that: First, note that the circuit is an emitter follower, and has a voltage gain less than 1. Second, R3 bypasses the transi...
The term "Discrete" uses to describe a signal with two modes. Wrong. Discrete means it can only take some values , not all values. I suspect by 'modes' you mean # of possible outputs. If we h...
In monostable multivibrators we use a trigger signal applied to the base of the transistor which is usually off to enter the astable region Can we instead have a pin which is connected directly ...
The current through the tunnel diode is: where $I_{f}$ is the current from the Shockley diode equation and $I_{tunnel}$ is the tunnel current. Is there an expression for the tunnel current or i...
Is it possible to drive a PMSM motor - here I am referring to an AC motor with permanent magnets(stator wounded, rotor with PM) - in a way that there is no externally mounted rotor position sensor(...
A diode mixer exploits the fact that the voltage across a diode is the log of the current thru it, to a good enough approximation for many uses. Now note that multiplication can be performed by ta...
in my schematic we must add R1 correct? No. Ultimately you are adjusting the varactor with a DC voltage that has a certain impedance. You can think of it as a Thevenin source. In your case, the...
I'd guess surge resistance and redundancy, rather than power dissipation. Looks like 10 stages of 5x parallel 2k going left to right?? So that's 10x400 = 4k. Perhaps used for parallel damping the...
My Comment I will begin my answer by commenting on the other two answers from two months ago. I will show that they do not contradict but rather complement each other. Ideal current sources. I ca...
I don't really have an opinion on this as far as scope goes, but this seems like a type of question that can be answered far more quickly with a dictionary. Hence, people might be tempted to vote ...
Suppose we have a sine signal applied to a inductive load. Is the inductance of the load changed if the frequency of the signal is changed?
Which will be the total series inductance?
Which will be the total inductance of this circuit? Quite simply, if both the individual 1 henry inductors are perfectly magnetically coupled then, the net inductance will be 4 henries. If bot...
I've seen a few different circuits (a) (b) (c) (d) described as "an O-ring circuit" or "an optimal O-ring circuit". What does the "O" and the "ring" refer to in such circuits? How do "O-ring circ...
I have finally downvoted the post of Andy "Very short answer - get rid of downvotes on answers" despite it is rather close, in some respects, to my own views. Let me clarify myself. I've never said...
