Ok this may be just my opinion and worthless but I like what I think, my brain is defective and does strange things like see humor in a post on the forum so I post a jokey reply to it. Often it is unwanted or people think jeesus what has it got to do with the subject post, much like what I have just said, I know what I meant and why I said it though.

I feel that many beginners are swamped by the math in electronics, likewise those who have already attained the level of expert then look upon those who have not grasped the basics as needing to find another field of work or hobby, as they will clearly never "get it". I think myself that if someone is not getting it then it is more a case of the teacher being a bad one or expecting too much of the pupil and having or giving no consideration or empathy with their pupils confusion.

Many of you will become disenchanted with things if your first few designs do not work, or if you simply sit reading a book / watching a video and feel more confused than ever before. Don't give up, walk away for a bit and then find another teacher or book or video that WILL explain it to you so you can understand it. Capacitors are my nemesis, and for years I had problems working out on a schematic which transistor was a NPN or PNP untll one day someone said to me that the arrow in a design pointed at the N material, that made it clear to me which was which in a schematic. Basically if the arrow points at the base it is a PNP. Little things like that make it easier to understand.

If you have problems with all the math like I do and think you can never grasp it all, then just go blow a few things up, I know a couple of people who, if they had started in college would never be where they are now, but they went and did the hands on approach first, learnt a few basic things and then when they worked out how x worked went and did the theory which was then much clearer to them than had they been sat in a room with some person throwing theory at them till their brain fried and they learnt nothing and gave up.

Never give up, never say I can not learn this, or that it is too complicated, not everyone is an Einstein or has the same level of intellectual capability as those above them until they get there. Those above you sometimes forget they were you or in your shoes at one time, they need to be patient and try another approach if you are not getting what they are saying. No one understands a baby going goo goo when asking you something but they grow up to be able to communicate in your language eventually ( I love that analogy ).

One of the greatest feelings I ever had was when I was stood in Maplins in Reading Berkshire, I saw a young lad of about 12 looking at a catalogue and the rows of bits on the shelves, he looked confused and worried, I asked him if he was alright, and he said that he didn't know what to buy as he couldn't find a capacitor he wanted for his project because they did not have it on the shelf, now me, I hate the things, but I knew that he needed to go higher in value to the next one in voltage to get what he wanted, and so I told him, he smiled a smile that meant more to me than much in the world and finally looked happy,got what he wanted and went home, I often wonder how much stress or worry that lad went through trying to work it out or if he was going to fail, how much time he spent looking for an answer or how much it made his heart sink he could not get the bit he needed, it was so easy for me to help him rather than ignore him or laugh because he had no idea. WE teach the next generation whatever our level of experience, if we dont then we fail ourselves. It is easier to make someone smile and succeed than watch them fail and hurt.

^^Like^^

Very good of you to help that kid out.

reminds me time when i worked in component store.. Lots of cases like that kid... Lots of comments, you know you could do ....

Sometimes things become clear with time when you force to study something in another discipline and then found a parallel that helps you to understand that old construction.

I remember that is University at electricity courses all we were doing calculating equivalent circuits more and more complex day after day and starting from some point that lost any sense and understanding. So I got virtual "pass" mark and forget about that. What was my surprise when reading "Art of Electronics" I found advice to consider 3 main parallel resistors configurations r-2r-10xR. I felt like I was treated by teachers... cause nobody ever tried to teach us that. We lived in the world or 43 Ohm connected to 121 and 477 Ohms some weird 13.5 times... and the idea was only a final digit. If it is off - you are out.

I asked a guy on work what is the resistance of 5 and 10 Ohm in parallel. He told me 5 and stared at me like "are you kidding me?!". When I explained why I was surprised he told me that always applied that rule why repairing his musician stuff and it worked.

Just was reading an article about transformer K factor (https://canadatransformers.com/k-factor/) and found a nice image of main sine and its harmonics.
Decided to "find that image in google" option to see if bigger resolution exists to save it for explanatory cases.

But was surprised how Google thought about this sine :)
