    Hey,
    I will like to first thank Mister Mo Ali for uploading these exceptional videos on UA-cam for free. I had trouble finding great videos explaining physics. However, I have seen many comments complaining about the language he uses to speak. If you go to the channel's about page you can see the location, which is Egypt. Egypt's main language is Arabic. Mister Mo Ali speaks in Arabic so that the students do not feel left out and stay engaged in the lesson. All the Arabic is either repeated in English meaning that you are not missing anything at all. Moreover, Mister Mo Ali has mentioned in his first community post that he decided to recreate these live sessions completely in English soon.
    That's all I have to say...

    Note*
    Potential difference means the energy required to transfer a unit charge between *two points*
    Emf means the energy required to transfer a unit charge *throughout the whole circuit*

    11:20 why does the rod gain electrons? Aren’t they insulators? Don’t they NOT want to give up their electrons? Why do they rip them off one material and take on the other?

    • @mariyam912
      @mariyam912 2 роки тому +1

      valence electrons are present on the surface. when friction occurs, they go on the other material. and about the second bit, yes they are isulators but they loose electrons to metals and share with insulators. Here we have to use only insulators. We know in covalent bonds they share electrons, the valence electrons...

    In the variable potential divider circuit (where we could control the voltage of the bulb by moving the slider), are we assuming the light bulb has no resistance? I'm asking because if the bulb did have resistance, the current would be split (as it's parallelly connected), & would have the full voltage regardless of the slider.

    I really appreciate your efforts, and am thankful to you for your work, but I would really appreciate if you were to consistently use one language.

      he's just saying the same stuff in Arabic it's not a big deal. also you should thank him instead of just saying what you didn't like abt the lesson. grow up.

    wtf with this language shifting?? I'm here for a physics lesson, not language one.
    Why did you do that, It makes everything even harder to understand!
    IMO this isn't great teacher move.
    You could've at least mentioned it in the title!

      I think this was originally made for his students and it ended up helping others
      So if you can’t understanding it or you find it annoying you can simply go watch another video which is strictly in English
