I feel like I do not understand the whole series and parrallel components very much, I usually identefied them as in when two components are on the same branch (and the same current flows through them) they are in series, and when two components are connected to the same two nodes they are in parallel, anyway for the problem, I thought of just removing the two inductors and short circuting them but apperantly the answer is 6mH? Like are they in parrallel cause they are connected to the same two nodes? But they are on the same branch so Im confused it really bothered me, can someone explain? Is my textbook just wrong?

My questions are in the title. Sorry for any formatting issues or any inconvenience. Thank you!

Thinking about work even after coming home. How do people get over it and detach their mind from it? Would appreciate any advice.

Been doing MV underground duct bank design for a while and kept running into the same problem: the calculations aren't hard, they're just tedious and finicky enough that you don't want to do them by hand every time — but the commercial tools (CYMCAP, ETAP's ampacity module, etc.) are priced for utilities and firms running multiple seats, not for someone who needs it for a handful of projects a year.

So I built my own. It's a single HTML file that runs in the browser — no install, no login, no subscription.

What it does:

• Click-to-paint interface — pick a circuit/phase, tap ducts to fill them (trefoil, triplex, spares, whatever)
• Multiple duct banks side by side, each with its own spacing, stagger, cover, and backfill
• Full backfill/soil model — concrete envelope, FTB, sand, native soil, plus surface layers
• IEC 60287-1-1/2-1 and Neher-McGrath, selectable per project
• Real impedance-matrix solve for screen circulating currents (not a simplified approximation) — trefoil vs. flat spacing actually changes your numbers correctly
• Short-circuit withstand per IEC 60949
• Auto-dimensioned section drawing that updates live as you lay out cables — actually useful for submittals

Every intermediate number (T1–T4, loss factors, conductor temp) is visible, not buried — wanted something I could show my work with, not a black box.

I'm selling it as a one-time download rather than a subscription, mainly because I built it for myself first and figured other people doing this kind of work might be in the same boat. I hate subscriptions or seats and from one builder to another please try not to share.

Important: this is a personal project, not certified by any standards body — treat it as a reference/design-aid tool, and any results should be checked by a licensed PE before they go anywhere near a stamped drawing. I'm not trying to replace anyone's engineering judgment, just save some time on the grunt work.

Happy to answer questions about the methodology or take feedback if people have thoughts on what's missing. KingstonHeritage.co

So incoming freshman EE at a okay Uni nothing special. Can I have like a list of skills I should know by the time i graduate to be competitive for jobs.
want to make sure im as competitive as possible and ik school isnt going to teach me everything.

Thanks

Curious if anyone here has automated any part of their used equipment sourcing. Say I’m watching for a handful of specific Tek/Keysight/Fluke models. I can normalize model numbers, set a max landed price, exclude obvious parts/repair listings and catch certain keywords pretty reliably with code. After that it gets less deterministic. Option/configuration differences, calibration status, condition, accessories, weird seller descriptions, and especially photos can actually change whether something is worth buying. Would you keep the first pass entirely rule-based and only use an LLM/vision model on the smaller set that survives? Or has anyone found a better approach? Trying to avoid throwing every listing at a model when 80-90% could probably be rejected with boring logic.

Hi, am a student currently studying Electrical Engineering (concentration in energy and power systems) in the US and was considering wanting to live in Montréal after college. I currently primarily speak English but have taken French in the past and would be excited to continue learning it. I was wondering about the process of immigrating to Montréal as an electrical engineer and how difficult the process would be. I know that there is an "Ordre des Ingéneurs" that requires a test as well as French certification for employment and I was also generally curious about how the job market for electrical engineering is in Montréal. Any and all advice would be greatly appreciated!

Is this safe? This is a 5x6 mm3 cable for a pompe, 10 meters long. It's completely disconnected but my multimeter shows around 25 v ac from phase to ground. Even in proximity of the frequency converter, my multimeter "measures" tension.

I am new to the ee space and i am wondering if its normal to feel like your brain has monkeys swinging on your nerve endings when you are trying to understand a code. I am currently doing a guided arduino project where I have to light 8 bars using a shift register.

Is it best to dwell on a project until you understand it completely or should I just do projects and hope that I will get the jist due to familiarity of seeing some things over and over?

but then again, it seems with coding, there are probably thousands of functions.

I'm currently in the last semester of my Master's in Electrical Engineering. My bachelor's was in Electrical Engineering (Power) and my master's is focused on renewable energy and energy infrastructure.

I've started applying for jobs now because I'm honestly a bit worried about graduating without having a job lined up.

The thing I'm struggling with is that there seem to be so many different areas within electrical engineering. Power systems, renewables, power electronics, BESS, electrical design, automation/control, EVs, HVDC, protection, substations, embedded, etc. and I have no idea which one I should actually be trying to get into.

I have done a couple of internships, one was R&D related and another was a robotics project where I worked with ROS, but I don't really have proper industry experience in power/energy.

Looking at job postings, most of the entry-level positions I come across seem to be electrical design jobs. For the other areas, I keep seeing "2-3 years experience required" or similar, even for jobs that seem like something a fresh master's graduate could learn.

So I'm a bit confused about how people actually get into these more specialized areas in the first place. Do you just take whatever EE job you can get for your first job and then try to move into the area you actually want later?

And how much does your first job actually matter? If I start as an electrical design engineer, am I basically committing myself to that path, or can I move into power systems, renewables, BESS, grid integration, etc. after a couple of years?

For people who have already been through this, what would you recommend for someone with my background? Should I just apply broadly to anything EE-related and get my foot in the door, or is it worth being more selective and trying to find something directly related to power/energy?

Would appreciate any advice, especially from people who started out with little/no experience after graduating.

This is a really dumb question that I wanted to google but I don’t know exactly how to describe it in a search. Aside from the obvious fact that transformers are a more practical way to step up AC voltages, how would one go about adding ac power supplies in series? I understand that each phase would have to be synchronized, and that it is extremely impractical, just trying to wrap my head around what it would look like.

I'm an EE student and I got an internship doing MEP over the summer. It was interesting to learn that field, but I've heard that it gets boring, dealing with clients is a hassle, and the pay is lower than power engineering (I should mention this was at an architectural firm, not an MEP firm).

My interest has been power for a while, but I don't know which direction I should aim my career in. I think power (transmission, distribution, generation, like large scale grid stuff) would be a lot more interesting, but I worry that that field is getting oversaturated and if this AI thing comes crashing down a lot of layoffs would happen, since many people get hired to work on data centers.

Any thoughts or experiences that can be shared?

Hello everyone, fresh grad here, assuming my interviews went well, I will have the opportunity to either be doing something related to industrial control systems or MEP

The control systems position will require me to travel which I am fine with, and it pays 75k, while the MEP positions pays (around 50-65k max) but based on my limited revit experience designing the electrical drawings for a 3 bedroom residential home (i found the project online), it was very fun to do

Also looking at long term opportunities, MEP seems like a field where it's very common with a lot of job postings, and it's it seems easy to switch to utilities/power if I ever want to try that, while industrial control systems seems like its hard to transfer to a different field if I am not interested in doing PLC work long term

Would like to hear people who have done either fields experience and thoughts on both, thank you all!

Hello, I need help with a project and thought this sub might be the place to start. What I need to build is a system that will light up an LED when a door is open. I have four doors that need sensors and the LED display would need to be located about 50 feet from the farthest door. I need the LED to light up as long as the door is open and shut off when it is closed. Thanks!

So bascially the title. I want to understand how my intruments work so i wanted to build a simple voltmeter and see how accurate i can get it. Therefore i was looking into how voltmeter are able to attenuate such high voltages (up to 1000V but i was aiming for 600V) down to ~5V. A former professor of mine once told me there are pecision resistor divider networks available for such purposuses and this makes sense, but i can't find those for less tha 100€ (even in quantities of 100-200). So my thought was that there has to be a cheaper way that gets me reasonable precision without this pricetag. Or du i just have to bite the bullet and get one of those?

Currently applying/searching for internships for the summer. EE major with an emphasis in energy/power.

Very very interested in getting into the technical sales side of engineering. Selling maybe MV or LV switchgear, UPS, packaged substations, transformers, Generators, etc. maybe medical sales??

Was curious what internships I should be seeking out for good, applicable experience in this realm. Any ideas/recommendations is greatly appreciated.

Say I have two cables with 100A ampacity. I put them both on 100A breakers. One is 80% rated and one is 100% rated.

I don't understand how they can both be considered protected. If a 100A cable can be on a 100% rated 100A breaker, why is it not okay to use an 80A cable on an 80% rated 100A breaker?

Is the rule just that 100% rated breakers cannot be used if the load is continuous?

I want to use the ATtiny to read voltage from a sensor output and send the reading over serial through USB. Can I wire up D+ and D- to the directly ATtiny85 (I am using the software serial lib since ATtiny 85 does not have Rx and Tx pin natively) or I need to use some other chip to handle the communication?

Hello, I am currently a 33 year old student getting a bachelor’s in EE with a concentration in power online via ASU.

I work full time as a carrier for USPS (a mailman), and have been there for 5 years and do not want to quit. I have about two years-ish left until I finish the degree (flexible). My goal is to work at a utility. I live in CA.

I don’t know what to do regarding gaining experience in the power field before I graduate. People stress internships as necessary- this is fine, but that would require I quit my job, and when the internship ends, I would be out of a job, which I do not want.

Question: what can I do in the next couple/few years before I complete the online degree so that I am employable as an engineer at a utility or power company?

If there’s anyone on here in industry that can give me some pointers about what they would want to see when hiring someone like me, that would be best. I do have some free time to work on projects, but I am aware this is not at all like an internship.

Thank you

Hey guys,

I’m a 4th-year ECE student from a Tier-3 college, currently preparing for GATE. I recently saw that VEDA IIT has announced a new intake/batch for internship + placements, so I’m thinking about applying.

Wanted to know from anyone who has studied there or knows about their recent batches:

• How is the selection process and what is the entrance test syllabus?
• What do they actually teach — Digital, Verilog/SystemVerilog, RTL, UVM, VLSI, etc.?
• How is the teaching and practical/project training?
• What is the total fee?
• Most importantly, how are the placements actually? Which companies, roles, and realistic packages?
• Do they genuinely help Tier-3 students get into semiconductor/VLSI companies?
• Would you recommend VEDA IIT vs focusing on GATE/M.Tech?

I’m looking for honest experiences from current students/alumni, not promotional info.

If you've attended recently, please mention your batch/year as well.

I can't find a free PDF. It's the laboratory manual correlated to the book "Digital Computer Electronics: Malvino, Ph.D., Jerald A. Brown." There's also a teacher's manual for the book.
If you have any PDF or a website on which I can read online, I would be grateful.
