The problem with the Internet is value, selection. and a huge amount of BS before you build the knowledge to detect obvious BS. The Internet is extremely useful for those in proper training or those with experience looking for specific information. As a place for learning I find it an abomination to a deeper understanding of basic facts to a beginner unless you are very careful to select sites like this one.

There are a couple of active threads on AAC that demonstrates this right now. The thread starter is receiving conflicting information from different sources on the internet. There are a sufficiently number of seasoned members here on AAC who are knowledgeable enough to be able to see through the fog and set him straight.

If you have any doubts about what you read on the internet, come here and ask questions and we will do our best to clarify things.

 

In addition to the book work, I prefer some type of group discussion.

Obviously, the AAC site is a form of on line group meeting, but there are many times I imagine myself asking questions to someone in a classroom.

 

You can visit https://ocw.mit.edu/courses/electri...s-and-electronics-spring-2007/video-lectures/

and sit in on a lecture or two .....

 

Can a simulator replace an electronics teacher?

Absolutely not.

In the hands of someone who already has a solid command of circuit theory and a lot of practical experience, a simulator can be a useful tool for anticipating how a particular circuit might perform, and a quick way of catching at least some design mistakes without expending the labor of breadboarding a circuit. It can also help in doing "what if" investigations, in which you want to see the effect of, for instance, changing certain component values.

But a simulator is NOT a replacement for a competent teacher, nor a substitute for a well-designed course of instruction in circuit theory. And in the hands of a total newbie, a simulator will probably do more harm than good.

 

Hello,

The US Navy Electricity and Electronics Training is already known and posted by @JoeJester in his signature:
https://the-eye.eu/public/murdercub...US_Navy_Electricity_and_Electronics_Training/
There is also the US Navy Electronics Technician series:
https://the-eye.eu/public/murdercube.com/Electronics/Electronics/US Navy Electronics Technician/
And the US Navy Information Systems Tech Training:
https://the-eye.eu/public/murdercub...cs/US_Navy_Information_Systems_Tech_Training/

Also the eBook on this site can also be downloaded.
Most of the eBook is written by Tony R. Kuphaldt.
There are also sections added written by members if the AAC forum.
Each volume has its own PDF on this site.
In the left colum you will see PDF version given.
Here are all PDF's in links:

They also can be found at the ibiblio site:

Tony also has written an other book wich is available here:

The problem all too often is that the person lacks sufficient knowledge to even realize that he is being set straight, so what he's told here becomes just one more bit of conflicting information-- or several more bits, depending on the expertise of the various people who respond to his post.

 

I know that you need someone to help you understand the basic of electronics but what I want to know is how hard can it be to learn electronics all by yourself.What happens if you create circuits without a guidance teacher?I remember I had a classmate in highschool who was middle in electronics and he didn't need help from the teachers.I guess he used simulators to help him create various types of circuits.Can a simulator replace an electronics teacher?

The answer is no.

Officially: If you learn by yourself, you will learn something, a part of the electronics, but how big of a part its not certain. It depends on the quality of your materials and on your effort. There are things that only a person can tell you(tricks of the trade). With books you can reach 80%, but most people only reach average, as its a lot of work. You will never be certain if you are doing it right, until you gain some practice.

Unofficially: we all learned it this way, the teacher only tells you where to look and SHOULD make sure you do not kill yourself. Yes its possible, but it WILL be dangerous and you will probably make mistakes until you learn not to make them. Do not start with medical electronics. If you are in industrial electronics be carefull.

Nothing in this life is gained without risk!

As officially I am dealing with idiots most of the time, I have to say this:
Do anything and use anything from my posts, which include only my own personal opinion, at your own risk! I am not responsible for any damage of any type cause to you or others!

In other words if you are stupid do not try any of this and expect me to take the blame for it!

And most of what is shown at Youtube fits that description. People with a camera, and not much else(knowledge) showing things that they don't know is nonsense to others that can't figure out it is nonsense.

One of the easiest things to get wrong early in the electronics context is 'Electricity'. While the actual words are less important than concepts it's also good to be clear. Electricity is not energy or current flow, we have other technical terms for that. In a copper wire and most conductors the electricity is the electrons themselves measured in coulombs, not in amperes. Electricity is the charge itself, not the charge-flow. Electricity in circuits is the medium for a separate entity called electrical energy (in Waves, Fields) developed from the separation of that charge (electricity). They are two different concepts that work together in electronics. If we start to think of actual electrons as energy carriers in the early learning process, it starts a misconception that can trap you into a mental framework that explains nothing as studies advance.

• In a simple electric circuit, the electricity flows slowly in a complete circle, while the energy moves differently. The energy flows rapidly across the circuit, going from the source to the load but not returning. The energy does not follow the circular flow of electricity; electricity and electrical energy are two different things. No charges of electricity are gained or lost as the charges circulate within the wires, yet batteries create electrical energy from chemical energy, and light bulbs destroy[1] the electrical energy as they convert it into light. Electrical energy takes a rapid one-way path from battery to bulb and then leaves the circuit as light, while electricity flows slowly around (and around and around) a closed-loop path and none is lost.

Must be something on your end KV. It just worked again for me.

Ok, I'm at the Uni today, IT blocked it, I'm sure (IT Nazi software). I'll give it a go when I get home this afternoon.

Hello,

@killivolt , The page also works fine for me.
I have copied the page to a PDF for you.

Thanks man. Enjoy your day.

Edit: I exported it to my desktop, I plan on taking an EE class after I retire July 1st next year. The University allows me free classes even after I leave. I have a friend that owns a TV repair shop, he's offering me 60k to start, not bad huh
