8.3 Electromagnetic Waves in Conductors / 8.3.1 The Modified Wave Equation

[@hershyfishman2929]

If you're wondering were 11:29 comes from, it's from the Binomial expansion: (1+x)^n = 1 + nx where x = (σ/εω)^2 and n = 1/2.

you are doing a very good work sir... i started watching your videos few days before. it feels really good!! you have made it very comprihensive...Thank you sir....

How are the expressions for kappa+ and kappa- obtained? Can u please elaborate the process, Sir?

[@mirzasofiqul3691]

where from get the value of k...

[@namrataiisc]

Sir if there is skin depth concept , that electic field reduces by a factor,inside a conductor..then why also do we say that electric field is zero inside a conductor...Do the answer is that former is electrodynamics and latter is electrostatics.

[@iqralatif6607]

Ur lectures are very helpful .Plz share section 10.3.2 from 4th edition ....

Can you explain the difference between free charge pf and free current. SigmaXE

[@BhanuChaudharyiitk]

Please add video for reflection at conducting surface and frequency dependence of permitivity asap I have my end sem coming

[@benjuliebenjulie7414]

this analysis is for a wave impinging on a conductor I assume.. For a transmission line would the analysis would be different??

[@chsajjad3427]

can you please explain or prove this term p(f)=e^sigma \e p(0)

[@josephksajan1298]

separate using variable separable method ie,partial derivative of rhof is taken on one side and that Dow t is taken with negative rho divided by epsilon ,and rhof on the rhs is taken on Lhs and just integrate

[@akashdas172]

your good sir but please could you just explain the k part in simplify form because its a long term and hard to remember

[@jg394]

I wish I could help some more. What I do is I look at what is constant and what varies. In this case, k is a constant. Outside of that, it's complicated but not really that bad.

[@joaopedrobravo8759]

yes, it´s very confusing. Cant understand de K part.

[@HaiderAli-hp6tl]

the only thing ur doing is just reading from there and copy pasting these simple concepts are easy what we need is some mathmeticall expressions like you should have proved the large value of K
