I am asking you if i can hired with the degree but no practical knowledge
Generally, no. You'll be competing with others for a limited number of job opportunities. People with experience almost always have an advantage over people who don't. There are exceptions, but that's not the norm.

I say again, it is not all in the amount of knowledge you have, but in your personal desire to learn.
History is full of those that made a name for their selves in spite of personal draw backs.
I hold up one example such as Michael Faraday as an example of a man who had no formal education and was forced to take a job of book keeper, one he had little interest in, but read every book on the subject of electricity etc, and went on to discover the basics of the simple motor.
Now his name lives in history!!.;)

Regardless of formal education, if you expect to be able to stop putting substantial effort in continuously learning new things, you will fail in electronics. Electronics engineers must learn new things, very often on their own using materials they must gather for themselves (data sheets, applications notes, technical journals, et cetra) all the time, by which I mean almost every week if not almost every day. A lot of good engineering is about attention to small details and even a fairly simple project may require leaning a bunch of new details.

Getting a job in electronics may put you in a position where you are able to learn a lot from people you work with, but it really depends on the situation and the people. Some work environments don't allow the senior people much time to help or teach the junior people. Some senior people are really good at teaching others and some are really bad at it.

So Max is understanding chemistry important in this field?What happens when you don't understand the chemistry of electrons,atoms,molecules,moles?
Is chemistry required in this field?
Can you understand electronics without chemistry?

For the vast majority of electronics, knowledge of chemistry (and physics) is not required. It helps in some cases, but isn't a requirement.

Many people use many things without having to have complete, or even cursory, knowledge of the underlying details. You can use transistors without knowing how to design one. You can use it without understanding what chemicals (doping) or physical topology contribute to one transistor being "better" than another.

But how can you understand how the circuit of a device works if you know nothing about electrons?Does it work by magic?I don't understand how chemistry is not related in this field but devices work by electrons,current.Can you tell me another way to understand electronics?Your message is confusing me a lot.

We don't usually think of electrons when we design circuits.

Let me use some analogies.
  1. Do you need to know how electrons flow in a battery before you can use a flashlight?
  2. Do you need to know how an internal combustion engine works before you can drive a gasoline powered car?
  3. Do you need to know the chemical composition of wood before you can use a piece of lumber?
  4. Do you need to know how to make ink before you can use a pen?
  5. Do you need to know how to make a pencil before you can use one?
  6. Do you need to know how to weave before you can wear clothes?
Does it work by magic?
No. At one time it might have seemed like magic, but only to uninformed minds.

I mean diodes and transistors use a lot of chemistry.Can you understand the use of them without chemistry?How?
I don't know if this is possible but I never heard of diodes and transistor that work by magic.I mean electricity afterall is a underbranch of chemistry.
What would be the use of Ge,Si,Al,Cu and more if you have no idea what these elements do?

They also make use of other scientific disciplines. Chemistry and physics are useful if you're working with devices like transistors and diodes at that level.
Can you understand the use of them without chemistry?How?
Easy, you just need to know know the basics of how they work at a macro level. You don't need to know how they work at a molecular level (as in manufacturing/designing them).

I know how to design logic gates using MOSFETs, but I can't build any MOSFETs. I know the materials needed to construct them and how to draw the layers, but I don't know the exact recipe used to make any. You don't need to know anything about chemistry to use transistors or diodes.

No one knows for sure the fundamental answers. That's why we have science.

We have theories. It's sorta like faith. It's what you're willing to believe.

Does someone that knows how to knit a sweater using yarn have to know how yarn is made? Does the person that makes yarn have to know how to raise and shear sheep or how to grow cotton or how to manufacture nylon fiber?

You only need to know the details to a level of depth necessary for you to do what you are tasked with. This is called information abstraction. In order to use something, we need to know how something behaves, not why it behaves that way.

To use a resistor I need to know how the voltage is related to the current (Ohm's Law), perhaps how power is related to voltage and current (P = V·I) and perhaps how the temperature is related to the power. Depending on what I am doing I might need to know some other things about it. But I don't need to know how to make it or, in most cases, how it works beyond the mathematical relationships it imposes on the items of interest to me (voltage, current, power, heat, temperature, etc.).

Middle school students (~12 years old) can understand how diodes behave without every knowing anything about what is going on inside the plastic or glass chuck that has two wires sticking out of it. Just knowing that if you apply voltage in one direction that current will flow easily with only a small, relatively constant voltage drop while if you apply voltage in the other direction virtually no current will flow. That is enough for them to do a lot of things with diodes. It is not enough for them to do other things, like designing a circuit to use a diode to measure temperature.

Electronics Technician

Electronics technicians complain of having too little control, work schedule, lack of accomplishment, no real opportunity for growth, no motivation to work hard, no say in how things are done, and mutual hostility among peers.
I found this in a article.Is that true?Do electronics technicians get paid poorly?Why?
Why do engineers in electronics get paid more than technicians?Are they more prepared for this job?
I read something else in a forum that said that technicians don't get a lot of money by repairing devices like TV or DVD player.
Here is the evidence...

More poorly than what? Engineers?

Engineers would typically be more educated and be able to do more than technicians.

Why would you pay someone more to repair a device than it would cost to buy a new one?

@wolly You cannot generalize like that, depends where you are/live what opportunities in your particular area, your abilities. education etc. etc,
Like just about any career, if you are good, people coming looking for you, and if lucky can right your own ticket.
All the ones that fall in the first line of your comment are probably not one of these.
I worked alongside Engineers and received the same money, purely because I could do their job and more.
Max.
