This video derives the boundary conditions for electrostatic fields. These are derived from Ampere's Circuit Law and Gauss' Law.

Thank you , really great Video , the only resource which I was able to understand clearly and follow.

Thank you! Happy to help!

good video ! in the min 5:20 , why the faraday law equals to zero? what about the magnetic field? it's a EM wave... and why in the integral take E as a constant?

@empossible1577 2 месяца назад

Thank you!! This video is in a sequence for electrostatics. The magnetic field term appears in a derivative with respect to time. This goes to zero for electrostatics. BTW...here is a a link to the official course website. It has links to the latest versions of the notes, videos, summary sheets, and other learning resources. empossible.net/academics/emp3302/

Great explanation. Would you please make a video on the electromagnetic Boundary Conditions?

@empossible1577 3 месяца назад

They are exactly the same, just that the terms are phasors instead of scalars. The magnetostatic boundary conditions are Lecture 5j here: empossible.net/academics/emp3302/

wow your lectures are really good. I wish you covered the entire griffiths book

Hi, I think " These are derived from Ampere's Circuit Law and Gauss' Law. " should be changed to " These are derived from Faraday's law of induction and Gauss' Law."

@empossible1577 4 месяца назад

Are you referring to slide 6 around 2:30? That first equation is Ampere's circuit law in integral form for electrostatics. Did I misspeak somewhere else?

@localfuture1484 4 месяца назад

@@empossible1577 I think That first equation is " Maxwell-Faraday equation " instead of "Ampere's circuit law"

Very clear explanation for dielectric to dielectric boundary condition. @15:08, If electric field cannot exist in the metal, why can we not say the normal component of the electric field in the metal is zero?

@empossible1577 2 года назад

The normal component of E must be zero inside of the perfect metal. However, the normal component of E is not continuous across the interface so the normal component of E in the dielectric does not have to be zero.
