- Let's explore how to calculate the emf and internal resistance of an effective cell when cells are connected in series. Both the emf and the internal resistances add up.

Best channel...tmrw is my As level paper 1..hope it goes well
You explaination is superb... I really enjoyed it sir.... You have made such a boring topic too too too interesting 🤩
Feeel agyi bhaiya ji
Thank u. Was in need of it
Such a amazing explanation.
Your explanation is so much easier than any others youtuber
Very thanks
best explanation ever ;)
Thank u very much
Wow
Now i understood better than my coaching centre
can you please do videos on mutual and Self-Inductance
2:12 but sir positive charge moves from + to - , wouldn't it be repelled by + terminal.
Ye but it will be pulled by the negative terminal of the adjacent cell. So the positive terminal of the first cell will repel it away into the negative terminal of the next cell...
ruclips.net/video/gwSbQBo55QI/видео.html this is their video on emf, internal resistance and terminal voltage, i think it might help
In short. yes
bro its not magnet
Post next video sir we are eagerly waiting..
You're voice is soooooo cute khan🥺❤
Is it the fact that internal resistance generates heat, the principle on which electric iron is built?
😮😮
MR SHENOY ...can i pls know which graphical system you use😍
Sketchbook, it's free!
@@KhanAcademyIndiaEnglish ARE U JOKING MR SHENOY🤭🤭🤭🤭 IT SHOULDN'T BE THAT....PLS TELL ME ...

Thank you 😂
i think your explanation is pretty much reversed ,and wrong .as according to batrery current could not flow if you connect posituve to positive ,i think so .
Movement of charges is what produce the electric current. So as long as that charged particle is moving in one direction..there will be current
Actually it's just an analogy as explained in his earlier video and the positive charge is just an metaphor of the direction of current...
