Thank you sir. I studied from your book (along with walker) in 1999. For past year and a half I watched few of your videos to help my niece. Thank you so much for sharing your knowledge on youtube. It helps a lot
I had many doubts when I was in 11th class in physics n 2011 but that time your videos were not available with such a great explanation and short time.
Electric Current does not obey the rules of Vector addition that is why Electric Current is not a Vector Quantity. However, it obeys the laws of Scalar addition.
Einstein's special theory of relativity introduced a correction factor to the mass in Newton's force equation (F=ma). The 'relativistic mass formula is that 'the mass of an object under motion is equal to its rest mass divided by the whole root of the velocity of the object squared divided by the speed of light squared, subtracted from 1'. (cant type symbols here). Thus as your velocity approaches the speed of light your mass approaches infinity. (Einstein had a different insight than this but this result is visible clearly in his formula)
Sir ,Kya magnetic field ki wajah se charge par force kisi instant par dekhne ke lia jo element magnetic field produce Kar rha hai wo bhi us instant ke kuchh samay pahle se rest par hona chahiye ?
For something to be vector it must satisfy 3 basic condition: 1)It must have magnitude 2) It must have a direction 3)And most importantly it should follow vector laws Since current has direction so it should be a vector quantity but since it doesn't obey the vector laws ,instead it follow scalar addition so that's why current is a scalar quantity. Is that enough explanation or it needed some more point to ponder about ? Thankyou 🙂
@@sanjayraval3028 current is called a pseudo vector. Tensor rank 1 but following kirchoff law for a neutral junction than vector law of addition. But indeed u r correct it is better to state it in broader sense : tensor.
Does current density is said as vector because of area is treated as a vector but its direction is based on direction of positive charge not on the direction of area vector (normal to area vector)?
Good evening Professor. I hope you might be aware of the section 5.1.3 of Electrodynamics by David J griffths where he has treated current as a vector quantity. Can you help me out here?
To be a vector quantity,the quantity should have magnitude+direction and also shud obey the law of vector addition..current doesn't obeys the law of vector addition
Sir I have a doubt from Fluid mechanics that according to Pascal's law if fluid is at rest then then pressure at every point is same but we normally know that pressure increases when we increase depth of a given fluid then pressure increases so my question is that where Pascal's law is applicable?
Sir What will happen if an accelerated particle is thrown in a magnetic field?? Will the velocity of the particle in the magnetic field will be constant,or will it increase??

Sir after your course on Classical Mechanics can you sir please oraganise a course on Electromagnetism or General Relativity, any one of the two elegant theories taking it to a little higher level for us to learn
sir, it's also possible that it might be a vector quantity that doesn't obey vector rules so it's also possible that vector rules are not universal. It's also possible that considering current as scalar can solve all the problems so no need yet we have discovered to treat current current as a vector ! ?
Hi sir , please elaborate tensor quantity its meaning and how moment of inertia and stress is tensor quantity and also about pressure when it have to call tensor and scalar .
Tensor is actually a very broad concept. Vectors are included well within tensors. A tensor, in mathematics and physics, is a mathematical object that describes relationship between objects in an algebraic vector space. A vector is merely used to describe relationships upto 3 dimensions while tensors are used to describe relationships in more than 3 mathematical dimensions. The Way tensors are used in class 11th and 12th to describe some quantities as being neither Scalar nor proper vectors is wrong and is merely a gimmick. Quantities like Moment of inertia, pressure are SCALARS which have a "sense"(direction) but do not obey the mathematical transformations of vector spaces. THEY ARE SCALARS. CALLING THEM TENSORS IS WRONG
Sir In the book IntroductionTo Electrodynamics by DJ Griffiths 4'thEd (p 219) it is clearly written that Current is actually a vector , I = (line charge lambda) .v . It is because the path of flow is dictated by the shape of the wire . With sincere regards .DrRahul ( your ex student )
sir....three elements resistor inductor and capacitor are connected in parallel to an ac voltage source ...then sum of all three currents is scalar or vector?

Topic dual nature of light Sir the energy of photon is define BUT THE MASS IS NOT Define And other can say rest mass of photon is zero Q mass of photon why not define ????"
It's because photon is "energy", it does not have a physical existence. A "packet" or a certain "amount" of Electromagnetic or Light Energy is called a photon. It need not have mass because it doesn't exist in any physical form(like blocks, or smalls balls), it's a form of pure energy. This answer is correct upto a certain limit and the more elaborated answer requires a strong knowledge of quantum and particle physics, which I assume, you do not possess at this stage. Hope my answer helps!

Sir my question is :-
Einstein said that if something could travel at light speed its mass would duplicate. How could it be?
Einstein's special theory of relativity introduced a correction factor to the mass in Newton's force equation (F=ma). The 'relativistic mass formula is that 'the mass of an object under motion is equal to its rest mass divided by the whole root of the velocity of the object squared divided by the speed of light squared, subtracted from 1'. (cant type symbols here). Thus as your velocity approaches the speed of light your mass approaches infinity. (Einstein had a different insight than this but this result is visible clearly in his formula)

Key word is that vector is only definable at a point of observation means quantity of vector at a point not quantity at the whole area
