the way professor uses (r) to denote vectors is the main cause of this confusion, try replacing (a) with (r) then integrate D.ds for top and bottom surface. Also, Z = h/2 for top surface.

There are few obvious mistakes in this video. I hope these are unintentional mistakes. First is that vector "r" in cylindrical coordinate system is shown from origin to the point. Where as Hayt textbook clearly shows it as radius of cylinder only. Second is the definition of the projection. The definition itself is wrong. Everything turned out fine in the examples shown because you are dealing with unit vectors. Consider vector r as not a unit vector. The definition will immediately fail. The actual definition of projection of vector B onto A is A.B/|A| Hope these are made clear somewhere in the erratta.

I want to ask why I_z = 0? I can imagine that a point on the exact line will have contrary forces that cancel out each other, but I don't understand the math-proving process.

Sir, is the projection of A on B equal to the projection of B on A? There is confusion in the definition of the Dot product you just taught. Kindly clear that.

sir , In the pn junction diode example if charge density is a function of x then there should be x term in charge density notation but you have given as qNa. then how will it be a function of x. if we integrate from -2xa to -xa we will get the same amount of charges. i dont understand sir. if i am wrong can u explain me sir.

@Growdaily602 5 ай бұрын
That was a constant density, we can simply multiply it with the length of the X direction, but sir shown it with integration and in both cases we get the same result....

l = a^2/L0 == some as if you were dealing with point charges rather than a line charge. You could have easily simplified the analysis by taking a differential slice of the cylinder and line charges.
