    Mahesh is so underrated,
    He deserves more attention and praise for his outstanding teaching ability, how he breaks down complex concept of physics into simple terms..
    great explanation, as always!

    Broo I'm literally being honest...i don't like it when teachers just give us a set of formulas to memorise and apply them in numericals w/out even making us think or ponder...I swear I literally liked this video within just 4 mins..You guys are the only one who actually gives the feel of physics....it's so saddening that khan academy isn't even popular

    No word can carry my zeal, nor could have any intelligent being that lived... Ay, the perpetual bliss but to reconcile with the wondrous beauty of nature that we are so devoutly yet unbeknownstly attached to. Let's have a time together to commend on the astounding process through which the great theories of nature unfolded unto mankind...Nevertheless, consciousness plays dice!(Prick a thorn unless you accord with the phenomenon of Quantum Entanglement)Right reverence and gratitude unto Sir James Clerk Maxwell who showed us to the portal of this great theory and of course to Mahesh sir, who reiterated it in words so rich, so powerful...

  • @yarenkaya7872
    @yarenkaya7872 2 года назад +4

    Quite explanatory; however, it would be even great if you had included the derivation of displacement current by using the equations of capacitors. Namely,
    C = Eo A/d(distance between the plates)
    Q = CV and V= E d
    Q = EoAE and EA : flux
    Q = Eo F(flux)
    then displacement current : dQ/dt which is Eo dF/dt
    Thank you

  • @philoso377
    @philoso377 8 месяцев назад

    Nice video and presentation.
    By page 3:50 presence of B at p confirms there is current flow through the vacuum between parallel plate and continue down the remains of circuit.
    Vacuum itself cannot pass charge unless it has permittivity which explains the B at q.
    So what is in the vacuum that pass charges? It was Aether, a fluid that has no mechanical but electrical properties, which is permittivity. Aether as a fluid attaches to all matter and drag directly with matter in the local frame and drag indirectly in the global frame.

    • @aerodynamico6427
      @aerodynamico6427 27 дней назад

      Not "remains" of the circuit; "remainder" of the circuit. And the presence of aether is still controversial.

    • @philoso377
      @philoso377 27 дней назад

      ⁠@@aerodynamico6427 “remains” vs “remainder”? have we turn this discussion into a grammar class?
      Yes it was controversial and not any more after this :-
      “Aether” is an incompressible fluid and has no mechanical but electrical properties where e0 permittivity and u0 permeability are measurable attributes of vacuum - Aether as important attributes of Maxwell equations.
      More importantly, it doesn’t blow through all matters like wind. Instead, it attaches and drag with matter in the near field in equal speed. On the other hand, Aether also drift at its own pace in the far field, deep within the universe.
      That is where straight shooters like M&M and Einstein missed the mark.
      --------------
      Moreover:-
      Einstein waited long on Michelson’s test result have lost his patient said this
      "Insanity is doing the same thing over and over again and expecting different results":
      “doing the same thing“?
      refers to (keep looking and failed to find fringing activity)
      “different result”?
      refers to (for fringe activities present that never recorded)
      -------------
      On the other hand he also said this :
      “You cannot solve a problem with the same mind that created it.”
      “You”?
      refers to Michelson and Morley.
      “Solve” what “problem”?
      To detect Aether wind by fringing activities
      False “Mind set”?
      That Aether wind blows through all matter.
      Correct “mind set”?
      That Aether attaches and drag itself to all matter at equal speed in the near field.
      That Aether drag complementing M&M’s test result - ie no fringe activities.
      Hope this catches your attention.

    and one more ..if there is change in magnetic field then ..opposite emf will be induced know..then opposite current which reduces the source current

    Sir why displacement current depends directly on permeability of free space ('Epsilon') but not electric flux

  • @Greg_Chase
    @Greg_Chase Год назад

    The 'host' for the electric field though in a capacitor with a free space dielectric.........
    *_is assumed not to exist_*
    and that is a big opportunity in physics. There is a notable wishy-washiness about the constituents of free space (aka the constituents of the vacuum) in physics history
    In our EE and physics courses in college, we were taught "electromagnetic waves do not need a medium to propagate"
    or in other words, "space is EMPTY"
    We carefully note that, in order to manifest the changing electric fields in the vacuum dielectric between the capacitor plates, THERE MUST BE A 'HOST' MEDIUM
    Why?
    1) electric fields fall off quickly with distance
    2) magnetic fields also fall off quickly with distance
    3) there are alternating magnetic fields, and there are alternating electric fields striking Earth this very moment...from our own Sun, from distant stars (the light and other frequency electromagnetic waves from them)
    The electric charges that originally created those alternating electric and magnetic fields ARE TOO FAR AWAY
    The host for the changing electric field in the vacuum dielectric between the capacitor plates must be charge carriers.
    Electron-positron pairs for example
