General Basics of Electricity

in this Topic, I will review with you all the electrical basics, Although most of us may know it or know most of it, but trust me, if anyone need to be expert in a field , he must be involved in all the basics of this field.

I will not explain in detail this basics , but I will put here summary files which be short but be enough to refresh your electrical basics totally.

so,please download all of these files, review it before we can proceed with some advanced Topic in the field.

  1. dear\eng.Ali

    It seems There is a problem in downloading.

  2. dear/ ganah
    please try again using Google Chrome and inform me.

  3. there are still a problem in download.

  4. it was saved but from another wireless.


  5. OK,ganah

    I upload the files to Google Documents because most of the file uploading sites may remove the files after a while.

    if you have any suggestion about this issue, please advise


  6. Dear Eng Ali
