Hey! Seeing all these comments make me sad, you did a great job for creating this video series. I was confused as to what Griffith meant when he said there's a discontinuity, but it all got cleared up when you said that the electric field flips the sign! Duh!
I find this very confusing. You have not emphasised what the perpendicular/parallel field is with respect to. (Perpendicular to the pillbox? the surface? which surface?) Notations and vector directions could be added for clarity.
You really didn't say anything unique aside from what was stated in Griffith's textbook. I assume that is what you were using to guide this video, but you really didn't elaborate anything to add to Griffith.

Exactly this, I had the same thing happen with Purcell :p
Griffith book + umm umm + confusion = your video
Thanks, cleared up my confusion of what the discontinuity physically meant
Need more videos like this, especially as a visual learner!
Also, i don’t understand why at 5:17 the sigma/ epsilon became negative sigma/ epsilon.
Very helpful! Thank you :)

Can u ..tell where we can understand better what is written there in Griffith's
@@koushalsharma7183 where😢
Sir plz describe this in your own not like Griffiths,tht would be more helpful....
great vid
Is E perpendicular means E A cos90?
The A vector is also perpendicular to the surface, so E dot A is the same as the perpendicular component of E times the area A.
thank you for the video sir!
hmm, but please write a little bit clearer and bigger, thank in advance :)
Lect here are merely the translation of griffits book lect , the same wording as written On the book and no additional material for understanding
100 people work is done it next
You have just dictated the text from the griffiths book. No explanation.
not good
