why is it not so in case of cars? we start them easily even if they are cool. they have same engines as we use in generators?
secondly what is the reason behind that a loaded engine or motor can't start?
Yes i am talking about generators whose alternators are rotated with the help of Gas or Diesel Engine.
here another question rises that Electrical part has nothing to do with the mechanical lubrication? what if we put the load on it without warming up?
I can't find appropriate category for my this question. I request you to answer.
why is it necessary to warm up an electrical generator for a few seconds before transferring the load on it? what if we directly put load on the generator without warming it up?
A Quick response will be...
Hi all friends,
I want to implement PI and PID controllers using microcontroller to make a CCPWM (Constant current pulse width modulator). need to make an algorithm for it.
help required from experts
I am using Proteus8.1 sp1 on my windows 7. I also checked it on windows 8 but on both It Suddenly Crashes after few mints of simulation.
To solve the Problem I have Completely Uninstalled it along with its all traces using revo uninstaller and regedit from my system and reinstalled it...
i dont know if it is a right place for this post or not but i think it is related to basic electronics.
i want to know about the relationship between light wave length and refractive index of the material. is the refractive index a changing property of the material?? if yes then why? if...
i am using orcad9.2 for my design. i am facing a problem in post processor. when i completed my routing i went to options--> post processor settings and get a blank screen with no layer defined???? now i am looking for how to proceed next to make my gerber file. i need guidance of experts...
i have designed a whole layout in orcad layout plus. but in the end when i try to make gerber file it gives the option that gerber viewer can't open the gerber file.
it is giving the following errors as shown in the picture below.
here it is showing many errors in each connection. i...
thank you alen ... i come across another problem regarding foot print creation... i make a foot print for led as shown in the figure below...
here if you see in left hand side i sketched a sstop layer line to show negative leg of led on pcb ... but i can't see any option in orcad to erase the...
thank you very much spudboy. please tell me one another thing... when i make a gerber file and sent it to manufacturer to make boards for me.... so how will it determine the size and other specific measurements of the pcb and the components of the pcb? i mean to ask do i need to tell...
i have created the gerber file in orcad using AUTO----> run post processor menu..... but there i didn't find any option of viewing gerber file... in TOOLS menu i didn't find any gerbtool option.... kindly tell me how can i proceed to see my gerber file and how can i take separte printouts...
Shortly... i want to remove the green blocks and yellow line of jumper form my pcb to get the bottom copper layer only.. how to proceed for that?
compare it with the fig below.
does garbar file contain the information of the board and component exact sizes???
I have successfully design my pcb on orcad9.2.. please see it in figure.
now i have a few problems:
1)I want to print the bottom and SSTOP layers sepretely on white A4 size pages. but the printer is printing exectly the same image as shown in figure above.
2) Secondly my software...
thank you spudboy. i resized the size of the board but can't find the AST layer in your indicated manu where top layer was selected. it is only showing 0,1,2,21,25,26 layers. rest of the layers are inactive.
