Why this is important?

Forums are all over the web. Some questions, get answer, some just neglected at all and the problem is you don't know the reasons. You know how to ask questions at the right time and in the right place just isn't enough when asking a question in forums, but it should be followed by the proper way so that interested forum members read it and answer the questions.


My first experience when ask something that mainly related to electronics forums made me realize something. It needs a few key points to get answered in a forum. The thread I created had a response a bit because I didn't figure out in advance.

Have you ever neglected in a forum when asking a question and no one answers it? Pissed Off? Actually, there are certain rules, procedures and reasons to do so. We cannot hope to instantly get the correct answer that quickly.

Members of the forum that you visit might be a busy man/woman so they didn't get to see all the threads and ignore the perceived less important questions.
We have to apply below steps before asking the questions in the forum. So are you ready?

Here is the reasons you didn't get answer in forum:

 

1. Make sure the answer of questions you are going to ask are not on the web or if the asnwers are on the web like Google, there may be technical or language barriers that are less understood. Try using Google Translate to translate it. If the results of translating less satisfying, try to explain clearly and fully in your question.

2. Try looking for a guide on your question, just maybe there's a manual somewhere.

3. Be sure to read the FAQ (Frequently Asked Questions) before ask and do a search in the forum. If the question was not asked on the forum you can ask it directly with a new thread.

4. Do a thorough search on Google or other search engines such as Yahoo to research these questions. Don't make yourself look ignorance and just want to get a rapid and easy answer without doing nothing.

5. We can do a discussion or ask a friend with email or mailing list, maybe they could give the answer.

6. At the time of the answer you're looking for is still not obtained after all efforts that said above, create a thread about your questions and explain in detail what we have done and the results we get.

7. Use a clear and bright picture if you would like to inquire about specific parts of the picture, do not use a camera that can't deliver maximum results in our picture.

The last thing might sound funny because my English is any less good, but needs to be emphasized when asking a question is try to make grammar, spelling and punctuation were rendered correctly.
Do your best even though our native language we're not English. Once you ask a question in the forum, don't be in a hurry to get the answer. Not everyone has a lot of free time.

I've seen someone make a question with multiple threads at the same time, they are impatient and want to get the answer immediately, of course this is not allowed. That's likely irritating people.

Learn about the forum that we entered. If you sign in to a television technician forum, do not make a thread title like "I NEED HELP!"or "PLEASE HELP ME!" Don't blame me if no one answered you.

In some forums there are provisions to include the name and model of the device you're question. Do with specific and clearly as "LG Flatron LCD Monitor Model L178WSS Shutdown Intermittenly". Just sit down sweetly and I'm sure this question will be answered within a relative short time.

Note the sentence do you use when used to designate a component, do not use words such as "That big capacitor". Better to use a more specific wording and details like "One capacitor 2200uF on + 5V trace"

Open minded and making it clear that you are able and willing to help in the process of developing the solution for yourself. When they suggest to read the manual or datasheet, do and give follow-up question if there are still less understood. Lastly, do what you need to do first before asking a question.

This article is not limited to electronics forums only, we can use the basic guidelines in this article to other forums so we can get answered in forum immediately. Don't forget to read how to use light bulb trick.

Have fun and thanks for coming here.

I always wonder the uses of zero ohms resistor, maybe you had too. As we know resistor were used in circuits simply just to oppose the flow of electrical current. It has the value that determined by the color of band on resistor body. You may not need this resistor when building the circuits on the breadboard, but sometimes we could find this zero ohms resistor in commercial circuit such a microcontroller circuit.
Why Zero Ohms Resistor
Picture by Wikipedia
Zero ohms resistor can be a wire wound type or surface mount type; it all depends on the boards. Any type could be adapted to the circuit as long as it does the job well. Keep in mind, this resistor different with current sense resistor since this current sense resistor attached to “sense” the amount of current being used by the load.
Why Zero Ohm Resistor?
Picture by Wikipedia
 Most of zero ohms resistor is available in 1/4Watt and 1/8Watt power rating, and generally marked with a single black band. Due to the fact resistor has a tolerance value. In other word, it still has some internal resistance which is very small like as 0.005ohms and it can be neglected at all.

Why zero ohms resistor used on circuits?

No exact answer for this as it depends on variety reasons. Why we don’t just use a common jumper wire like we do on breadboard since it's just like a simple “conductor”?
There are many reasons behind this question.

The common reasons are:
1.    Most of manufactures use a machine that automatically inserts the components on the boards. That is not an easy job to produce a thousand even a million boards manually. In some cases, they need to connect two points on the printed circuit board and the downside is an automatic machine couldn’t “grasp” the jumper wires. Please never imagine manufactures will insert the jumper wires manually. The other reason is the two points that connected with zero ohms resistor could be used as a test point to measure the current during development and testing.

2.   The engineers have a plan to change the resistor if devices don’t work as their calculation. This will give a flexibility to remove that zero ohms resistor and use more reliable components on printed circuit board.

3.    Saving cost, yes you hear it right. The printed circuit board, especially single sided board is much cheaper than double sided board and that is one of reason to use this resistor as a jumper wire. Double sided board uses a vias to connect the traces and it can’t be applied to a single side board.

4.    For a good looking printed circuit board. The circuit board needs to look neat and inability to connect some points on PCB due to other circuit paths make the designers have to use this zero ohms resistor as well.

Well, at least the circuit boards are still working well and we don’t have a problem with zero ohms resistor. Electronics just like a puzzle and it was fun to learn all about that. If you have some thought, I would like to hear from you.

Thanks for coming here!
