Meaning of GND and ADJ Symbols in Electronic Circuit Diagrams

i saw in some circutes,the symbol GND and ADJ .what is this?. and you just see the picture. what is this symbol? canyou discribe about it?

Gnd is ground, sometimes the negative of the supply. Adj is commonly found on adjustable voltage regulators and is the pin used to "adjust" the output.

There are 3 types of grounds - earth ground, signal ground and the one you have shown is referred to as chassis ground.

As for the adj - it means adjustment, unsually in reference to a variable resistor, capacitor or inductor.

Not another third year electrical engineering student is he ? Blimey Stroll on

They beginning to sound as bad as some of the new Entrepreneurs who have just bought out entire companies without so much as a service diagram , parts , contracts with oversees suppliers to ensure the receive schematics

Then go bezerk and wonder why they are in so deep they cant get out of this mess

I’ve never met so many professionals who are this technically minded , running electronics , electronics consumer industries , it related fields and don’t know what they should be looking for before they buy or import from abroad

Most of them dont seem to know how to read a schematic either never mind indentify parts requirements or what the future holds

Senseless blind stupidity some of this

No wonder the country is in debt and we have this international crisis Is this normal I ask ? or am I missing something here

I think whats more amazing than anything elese is these are the ones who are shouting all the odds but havent got a clue themselves they are

Also the so called high paid earners some of them further the most impatiant at times expecting all thier requests to be actioned over a a couple of days ,the most rudest of all people the worst payers in history and actually not worth doing bussiness with

Does make you laugh this It definatley makes me laugh

do you know that this knowledge source exist?

Hi Mark, obviously you have witnessed or have been directly affected by one of these young and incompetent engineers, but i do think you owe Vishnu an apology.

You start your speech of with a question, " Not another third year electrical engineering student is he ?", but obviously you didn't care because you went straight into typing out every negative thing you could think of about young engineers/entrepreneurs. What if he isn't a third year electrical engineering student, what if he is a first year who is reading a head and came across something he doesn't understand, what if he is a teenager interested in engineering and has a few questions, what if he isn't an engineering student at all? Well if he is a interested up coming engineer, you did a great job motivating him!

I'm not saying you are wrong. I'm 100% certain there are young engineers/entrepreneurs out there who abuse their power and authority, but this particular forum is not the place to express your views! You could quit easily start your own forum!

The reason why i felt the need to comment, is because i am a third year electrical engineering student. I think this website is great at providing a means for young and future engineers to ask question, no matter how trivial the question may be. I feel the way you conducted yourself in this forum and belittled Vishnu, without even knowing anything about him, was highly disrespectful and selfish!

On a positive note, I would hate the idea of someone having the views you have, towards me one day. So i promise to respect and positively engage with anyone that i work with or for in the industry.

I’m really worried Can you see the look of concern on my face “No !!”

Unfortunately for some of you I have also been into the field quite extensively and if that is the standard I’m not impressed so irregardless of company and watching just how many companies are collapsing because of these standards

Its necessary to be negative Possibly your opinion cruel may be so but that is how you make people go out there into the wide world and research and do it properly!!

That’s how I was taught both at school and at university some teachers lectures very sarcastic or so it seemed at the time

I managed to get through and they were excellent teacher’s lecturers

Encouraging people to be lazy doesn’t make them learn you have to adopt a hard approach sometimes If you don’t like that well my answer is you are just going to have to not like this but it works and it works well

Correct

Im totally upfront and I don’t believe in hiding the truth to make people happy making people happy doesn’t always produce the required results

Finally he’s quite capable of using Google to look up a very simple question bearing in mind he is a third year student and would know how to use the net If he’s doesn’t then he needs to go and do a simple basic course on how to use the internet AND

IF HES POSTING COMMENT HERE THEN OBVIOUSLY HE DOES KNOW HOW TO USE THE INERNET

Yes very rude much needed I’m afraid !! especially when you see a director or group of directors waste 25 grand esepciallyb when you have to try and sit thier and sort the balsterd mess out Dead right im going to be rude

Like it or lump it in other words

Again Mark, where does it say he is a third year student?
