guys ,here u can see a typical LM7805 regulator circuit and potentiometer circuit,see the ground connection,i think those ground connections should be connected to the negative terminal of the power source!

please tell me are my assumptions are correct?

 

please help me guys!

 

please help me guys!

They are connected! Do you see the - sign by the battery symbol?? That IS Ground......

 

Learn to read schematics and learn some basic electronic stuff before you go about trying to build stuff.... You can not read circuit schematics, You can not use google to find your own answers, You don't even know how PCB's are made, you do not know how to solder,.... Is there anything you do know??? Or are you expecting everyone to do the work for you?? Would you like me to build the whole thing for you???


Try things on your own, before asking questions that are unnecessary........

 

sorry,what all the matters u said that i dont know,for gods sake,i know all that basics.i just wanted to confirm,and u know that images were created by me.

 

Those circuits were created by me !i just wanted to confirm that am i right!as i am a computer software engineer,i am studying electronics from 8 months on my own in my home,i had a doubt on ground in the schematics,so i asked u that doubt!if i had irritated u please please forgive me,please bmorse

 

aj silverthunder,

Don't worry about a thing, everyone has just been a little frustrated with all your posts lately. Try to ask the same general questions on threads you deem similar. Your assumptions are correct, BTW. Whenever you see that ground symbol, you can connect it to the negative ternimal of a power source.

There's nothing I need to forgive aj_silverthunder, I admire your motivation to learn and verify your conjectures. I do, however, have one suggestion; try researching the internet extensively regarding electronics via the internet. Many of the questions you have asked can be answered by means of AAC's e-book and by a multitude of other resources online.

guys how do they select the RF choke,i mean on what parameters do u select the value of the RF choke.like the power supply,voltage,etc...please help me !
