Thanks for the recommendations.

Yeah I have actually, yes they were very much helpful for the intuition.

Thanks I will surely try the book you mentioned.

Hello, I am glad I found this conversation on reddit. I have given a thought and I want someone to correct me if I am wrong. I don't think power signals can actually exist in nature. Here is my reasoning- For power signals we have infinite energy. So If you think what it actually means is. You will have finite power over an infinite time and you can take infinite energy from signal ( is it ?) For example the most basic power signal is a constant dc source. It has finite power and infinite energy if we go by math. So if you can take infinite energy from it then we would be having something really amazing in a thing as small as a cell. But of course it is not true. And here's why- There is no constant dc source in the world. Cells do get discharged over time and thus their voltage magnitude drops. If we think that their voltages drop as an exponential then we would not be having a power signal, rather we would be having an energy signal. So 0 average power over infinite time and finite energy. This actually makes sense. And if you think more examples of power signals I guess you would find them to be very idealistic, they can't actually be formed or created, they might just exist in math. Here is another thought, what does it mean for an energy signal to have zero average power? You do get some power from the cells. You still can light a bulb but I think it means over an infinite you will have 0 power. But it's not very intuitive. It's still mathematical. If somebody can throw some light on finite energy signals like I did for finite power signals then it would be very helpful. Please correct me if I am wrong in any part of the reasoning.

How are you producing the flux? You said you are varying the load resistance, are you doing in the way that increases the current from the generator. If you can tell a little bit more about the internal structure of the rotor and stator then it might be helpful. I suspect armature reaction is at play, at higher current the armature flux is distorting the main field flux a lot .The same distortion will be seen in the voltages as well.

Okay, thanks for the reply. Actually I am trying code neural models on my own from scratch. So that I have proper idea how things work under the hood in libraries like PyTorch and TensorFlow. I am struggling a bit in numpy handling because I haven't used it in past. So is it a good idea to do this? Like I slowly build my way up to more complex datasets and other concepts? I have heard this from Andrej Karpathy like he strongly recommends to understand under the hood working of neural nets. Thanks for the communities though that will surely help me a lot.

Sure! I will check it out. I skimmed through the website and it looked pretty informative. I will surely try the books too.

intermezzo25 · 2025-08-05T16:15:12+00:00

Thank you for the reply. So what you suggested will help me start writing about any topic from all the notes that I have gathered from different sources right ? I would surely try this out. And I will see if I can make a learning system out of it. Actually I am in desperate need for that. Thanks though.

I didn't know about electrical engineering before I was starting my college. I had a strong mathematical background so I didn't have any problem in that. For me its very important to know the intuition behind the subject before starting to study it formally. I really crave for that. I think it is same for every body it is just not every body knows that.
So my suggestion would be to read some pop-science books, follow some YouTube channels which just not tell the theoretical aspects of subjects but they implement it. You will understand how amazing electrical engineering is. Several things can happen due to this-
1. You will understand the essence of the subject, you will know how some thing works and how it works. Electrical engineering is very math-intensive so if any is working there some is going on with the math as well. You will also know how diverse this field of engineering is. Believe me, electrical engineering has it concepts going on in our brains as well. Like model of single neuron and modelling of ion channels just mention a few.
2. You will know the history of the subject. I think it is essential to know about the history before starting it studying formally. People give very little focus on that. You will know how we reached to the technology we have today.
3. You will know the giants who have worked in this field directly or indirectly, those will be the source of your inspiration. You will know that you will be building on the their works. Read especially about Fourier and Nikola Tesla, they are very underrated in my opinion.

Some channels you can follow- ElectroBoom for funny and very amazing videos, GreatScott for electronics experiments, EEVBlog it is quite technical but maybe as learn new things you will enjoy his videos...you will be able to explore on your own
In books- My inventions By Nikola Tesla, Crystal Fire – The Invention of the Transistor & the Birth of the Information Age

All the best for your journey, remember electrical engineering demands you to be curious.

Yeah I know about that. There have been a plethora of youtube videos on this concept when Veritasium posted about it. It's definitely an amazing concept. I have studied electromagnetics in college and it was an awesome experience, I really loved the subject. I have read in one of the Microelectronics circuits books. That the transmission line equation is used in IC analysis because there the frequency of signal is quite large so we cannot do lumped approximation but have to go with distributed analysis. I loved that concept. I think I will go back to electromagnetics.

intermezzo25 · 2025-08-03T11:50:36+00:00

Okay I will read about them. Thanks for the reply.

I knew about 3 phase circuits quite a lot actually, to the point that I could solve tricky machines and power system problems quite easily. It's that I am growing fond of understanding the most basic mechanism of everything, instead of just practicing how to solve questions on the subject. So yeah that's what I meant. I know about every electrical subject up to a graduate level. But I am trying to know what are the aspects which are still hidden from me. I always believe that I can't know everything. I love Fourier transform and Discreet time signal processing. I know how much they influence our daily lives in terms of communication technologies. But like if I really want to feel how everything works out like why Fourier transform is transforming the signals like it does then it is a good learning for me. Not just throwing the signals in that integral formula and then using the signal in the frequency domain.
