Good evening,
I'm just getting started with some Keysight equipment (specifically EL34143A DC Electronic Load). I've recently been messing around with BenchVue to do some tests for DC power supplies and batteries, and can't find too much technical detail on the website or any other areas. I'm...
Hello everybody :)
I am trying to read the values from a direct drive linear motor's (SDLM-025-095-01-05) inbuilt encoder using a NUCLEO-F446RE board. It is a straight forward task, but I am slightly confused with the cables. ( datasheet )
Overall, the motor itself has 10 cables (as seen in...
Hi,
I was working on a thesis project on a portable ECG device, I checked these

Hi All,,
Can i daisy chain two controllers so that it can be operated at two different locations (Won't be used at the same time). I need to bring in controller located outside back in the mechanical space area. Anything special i need to look at?
TIA
(Edited):
It's an industrial air...
Hello good friends. Im curious in a strait way about dielectric absorption. Particularly the current. Where does the current come from? (If i were to elaborate, i would say people familiar with a capacitor that has been shorted for long (hours/days) durations will notice that upon disconnecting...
Here, I want to use Thevenin with those 2 resistors in the base.
How can I combine those two resistors with thevenin or do you have any other better idea to combine them? (circled with red in the picture)
(PS: I don't ask the solution of the question. I'm only asking individually the...
Hi, I just have solved one of the bjt common emitter question below.
However, I'm curious that how can I additionally find those things below:
1) Input and Output Impedance
2) AC Gain
Here is the example and my hand draw solution. However, the question only asked to find Vout/Vin...
Also, my...
While I was converting this with the inverse phasor transform, I wanna ask a question
P{ -4 cos(200t – 45°)}
Should I say -4∠-45 or 4∠-45 ?
I mean, do I have to preserve the negativity of the magnitude which is "4"?
As far as I have known that the magnitude is not a vectorial thing and then...
The was an equation given like that:
v(t) = 5cos(1256t-pi/4)
Then I wanted to draw this graph below:
Do I need to scroll the chart left or right? (In the cosine graph, I shifted it to the left side)
Also I want to ask that, I have been always encountered with sine function graph drawings...
Here is the i (graph a) and i^2 graph (graph b) for the RMS calculation:
My question is while calculating RMS value, should I decide to determine the period by looking a) or b) graph?
Because, while I'm looking for the a. graph (shown above), I guessed the period is 2pi
However, if I would...
Hello, there is a subject I need to research, but unfortunately I could not find a detailed source.
I would be very grateful if you could guide me to investigate. So I can go on and read it myself.
Thank you very much in advance, best regards ...

Actually I have been thinking this question since 1 week inside my head.
As far as I know that those functions are coming from "Euler's Equation" but I still concerned that what such kind of real life things are making cos and sin functions are so important for us?
I just know that those...
Hello, I am developing my degree work on the coordination of hydraulic and thermal units in an energy network and I was wondering if there is any test network with which I can evaluate or compare the results obtained with my work. Thank you very much in advance
Hello All,
I am a young professional electrical engineer who has just started working in Automation field. We build customized panels including PLCs, HMIs, Pushbuttons, Lights, Relays etc., I have been searching for a reference codes and standards that can be helpful for designing and wiring...
I am working on a static transfer switch which aim is to allow supplying a load with 2 different sources in order to have a redundancy when feeding the load. The head to tail assembly allow the current to flow in 2 directions (for each alternative of the input current)
The working condition is...
Hello Everyone,
I am a young professional who has just started working in automation Industry as an electrical engineer and looking for a light scale software to develop electrical wiring diagrams for automation projects. My circuits mainly consists of PLC, HMI, IOs, E-Stop, Switches, Sensors...
For Question 2.1, is the power 500W or 100W ? Do we need to apply the passive sign convention rule for power in whatever cases? Also, i’ve Learnt that we can check answers by balancing power in a circuit. But the power in this kind of circuits don’t balance out, but it is still valid. So when...
Hey everyone :)
I'm working as an automation engineer and I've always asked myself why people say, that for example birds, can sit on power-lines, because they aren't touching neutral/different potential and no current is flowing. I can't really get this explanation into my head, because...
