Recently we created a poll on our channel and the outcomes were disappointing.
Join JEE Main Practice Test Series (only 349/-) - www.isacdigita...
We asked the students why the current is a scaler quantity?
98% of students answered that it is a scaler quantity because it doesn't follow the vector law of addition which is a wrong explanation.
Because current density is a vector quantity but it also doesn't follow the vector law of addition.
Many students came up with the assertion that current is a tensor quantity which is an obvious thing because every quantity is called a tensor and then we have different degrees of those tensors.
In this video, NMS sir came up with the correct explanation why current is a scaler quantity and why current density is a vector quantity.
Moreover he also discussed the real logic behind calling quantities as vectors or scalers.
Check out the complete video to unlearn some wrong concepts and learn a new fundamental concept about vector quantities.

I don’t know why YT showed me this video. After watching this and after checking the confidence of this person let me add something. Tell me one situation where current follows vector laws. You will not find a single situation. While calculating magnetic field we don’t take current as vector we take “current element” where we associate small element “dL” which has direction not the current. Similarly in current density we take projected area which is perpendicular to direction of current so that projected area makes it vector not the current. Also you can treat it like charge density times velocity,here velocity is a vector. In AC calculation we add two currents as a vector but in AC it is not a vector it is a sinusoidal quantity which has some phase and frequency and if we add two different sinusoids with same frequency and different phases then we are actually adding their instantaneous values and it follows phasor concepts not the vector concepts. You can say that two sinusoids of same frequency but different phases can be added with the help of phasors and it is similar to vector addition. We are actually adding two sinusoids of same frequency to get a new sinusoid. Tell me one situation where we take current as a vector. You will find none. Moreover it is not like “jaroorat k hisaab se define krtey hn…”everything in physics have meaning and significance. Let me tell you one more point VerySmall angular displacement can be treated as a vector coz it follows vector rules (standard) while the large or finite angular displacement can not be taken as vector coz it violates the basic rules of vectors. So it’s not like” jaroorat k hisaab se define krtey hn” there are standard rules which must be followed by vectors. For deeper understanding read “The Feynman lectures on Physics volume-2”chapter-2 section 2and 3 Volume-1 Chapter-11. From where this confusion came from? When we add current in AC sinusoids (same frequency with different phases) then we can add them by taking it like a vector whose magnitude is max value and phase as angle. Now one more request in this video he is showing that he knows more than others please take a pause and calm down.

Current is a scalar as it measures the net charge flow rate through a cross-section, direction-independent. Current density is a vector as it describes the magnitude and direction of charge flow at each point, essential for modeling current distributions and applying Maxwell’s equations in electromagnetism

I don't know why he is just saying crazy things, no derivations, no proof Here are some popular physics and electronics books that support the answer: 1. "Halliday, Resnick, and Walker's Fundamentals of Physics" (10th edition) - Chapter 28: Electric Current 2. "Serway and Jewett's Physics for Scientists and Engineers" (10th edition) - Chapter 26: Electric Current and Resistance 3. "Giancoli's Physics for Scientists and Engineers" (4th edition) - Chapter 25: Electric Current and Resistance 4. "Kirkpatrick and Wheeler's Physics: A World View" (8th edition) - Chapter 24: Electric Current 5. "Nilsson and Riedel's Electric Circuits" (10th edition) - Chapter 1: Introduction to Electric Circuits In these books, you'll find that electric current is treated as a scalar quantity, with only magnitude (amperes, A) and no direction. However, the direction of current flow is often indicated in circuit diagrams and discussions. Additionally, you can also refer to: - "The Feynman Lectures on Physics" (Volume 2) by Richard Feynman - Chapter 23: Electric Current - "Electricity and Magnetism" by Edward M. Purcell - Chapter 1: Electric Current These books provide a more in-depth understanding of electric current and its behavior, reinforcing the concept of current as a scalar quantity.

Current is a scalar beacuse it is defined as charge passing THROUGH A PARTICULAR CROSS SECTION IN A GIVEN TIME PERIOD. So CURRENT HAVING DIRECTION DOESN'T MAKE ANY SENSE. Current density , however, has a direction as it is defined at a particular point (in di/dA, area tends to zero) so it is always a vector. PLEASE REFER TO PROF. HC VERMA'S VIDEO ON THE SAME TOPIC.

After seeing your catchy thumbnail, I decided to watch the video carefully. After viewing the entire video, I tried to identify any misconceptions or new concepts you introduced, but I found none. I'm also puzzled by your claim that 98% of students misunderstand this concept (I'm curious about your source for this data 😝. Proper references and justification are needed if possible). The diagram you drew on your digital board illustrating current addition in branches is based on Kirchhoff's Current Law (KCL). Current always follows this law. It's a well-established principle in physics, which uses scalar algebra, not vector algebra. Therefore, if asked why current isn't considered a vector, one can argue that since current doesn't follow vector addition, it isn't a vector. This explanation is accurate, so I'm not sure why you claimed it's incorrect.

1. Electromagnetic Theory: In Maxwell's equations, which form the foundation of classical electromagnetism, current density ( 𝐽 J) is a vector quantity because it describes the current per unit area flowing in a specific direction. However, the total current (I) is the integral of the current density over a cross-sectional area: 𝐼=∫𝐽⋅𝑑𝐴 limits A Here, the dot product 𝐽⋅𝑑𝐴 J⋅dA results in a scalar because it represents the net charge flow through the area 𝐴 A. This integral sums the contributions from all infinitesimal area elements to yield a single scalar value for current.😅

The question could be framed in a more intriguing way: Why is current considered a scalar even though current density is a vector quantity? Additionally, current is never treated as a vector in electromagnetism. In Lorentz's law, the velocity of a charge is considered a vector, and the length of a wire is also treated as a vector. However, current is always considered a scalar.

You are right. Theoretically the statement is correct a & and of course it can be validated practically..it is well understood, that current is basically flow of charge and resultant of 3 & 4 amp at 90 deg will give results of 5 ampere but total charge was 7 originally. Where has remaining 2 unit of charge gone? ....so it will not disappear any where because charge is conserved and therefore it is not vector quantity as it does not follow vector law of triangle addition

That one teacher who says 'mere method se nhi kiya beta to galat hai' He needs to keep his ego aside for such kind of videos. Such type of videos are appropriated but ego that he carries that only his method of explaining something is the only method is not good for any teacher. The point he made that teachers explain current ki vo tensor quantity hai, i agree to this because there is a lot of confusion among teachers that tensors are third type of quantity along with scalar and vector. But i disagree with the fact that he thinks explaining that current is scalar by stating it does not follow vector law is wrong. As anything can be disproved using various methods. Their are plenty of reasons that current is not a vector, and not following vector laws is one of them. Students at 11 and 12th level will not get all the tensor stuff, so they are given the simplest reason. He himself rant for 10 minutes without explaining why the statement "current do not follows vector laws so they are scalar" is wrong because there is nothing wrong with the statement. It is just one way you can explain why current is scalar their are several other ways. I respect the kind of series of videos, but keep the ego aside that will make you the only thing you are going against. Their is no place of ego in physics. Even the greatest mind of all time disagree, but they learn from the discussion and move.Peace ✌️

We use equation of continuity in most of the cases. If u r at 12th level, u might not understand, but the divergence of current density is the rate of change of charge density. Dot product of current density with surface element gives electric current(Mathematically current is scalar too).

It is indeed deeply saddening to see the PhD candidate with unclear concepts being selected in a top research institute like TIFR. As for the explanation, it is very simple and doesn't demand a video. J vector= I/ A vector ( has both mag. and direction). Similarly, J=σ E where E is a vector and in J= ρv ρ= charge density and v= drift velocity of charge carriers. This makes J a vector. And as you know, vectors, scalars and dimensionless quantities all come under tensor matrices, just the orders are different. Thank you.

Another analogy though unrelated. Despite having direction and magnitude, angular displacement is not a vector because it does not obey the commutative law for addition. But when dealing with infinitesimal rotations, second order infinitesimals can be discarded and in this case commutative property appears. The direction of angular displacement is different from that of linear displacement for two reasons. First, it points out of the plane because of the nature of angular displacement. It signifies a rotation, as such, there is not any particular direction unit vector in every coordinate space that could represent it. To signify the direction of something that points in every direction on a plane, it is easy to specify it along the one direction we can be sure the linear displacement isn't pointing normal to the plane. This is a much used convention (such as with area vectors, torque, and many others). As usual as well, we use the Right Hand Rule. The second, and perhaps more important reason is that we always want to ensure that the angular displacement does not correspond to any true displacement that would be in a radial direction. Sorry for copying, I was too lazy to type.

Not True. Current as shown in wires and circuit has one degree of freedom as it can travels only along the length of the wire , hence scalar so direction is not important. Even in the case of Biot Savarts law the direction of velocity of electron is taken into account rather than the direction of current. Velocity is vector, Current along a wire isn't.

Sir, I heard you are an IIT graduate. And you don't know vector clearly! Surprising! For school student we can define vector as quantity having magnitude, direction, & obeying vector law of addition. There are many quantities having magnitude & (sense of) direction, but not obeying vector law of addition. They are not vector at all. Please note 'obeying vector law of addition' is a necessary condition for a quantity to be a vector. Unfortunately, many (low level, non-rigorous) books do not state but tacitly assume this. For BSc student we can define vector more strictly like this: Vector is a combination of 3 quantities that transform when the coordinate axes rotate according to a definite law. Sir, please read a good book on tensor. You don't know the motivation behind the definition of vector. Once you know it, you will feel embarrassed trolling on those 98% you said wrong. You also seems not knowing the full significance of current density vector. Current density 'j' obeys vector addition law because it works for differential form, but (dc) current 'i' doesn't because it is for integral form. How!? I hope you'd enjoy thinking over this! Many errors in your conceptual understanding! I pick up only two. I ponder over why such errors! I think this is because entrance & board exam never ask deep question on concept, but only definition &/or application type questions. PS: I appreciate your attitude of 'not taking anything for granted' but deplore your trolling nature & overconfidence in your understanding.

Read it carefully before dancing for debate !!!!! If you take any reputed book then it is clear already. They don't just say only about magnitude and direction but they mention about line of support or they use the word meaningful direction. Most of the students say it doesn't follow law of vector addition ( by keeping intuition about meaningless direction ) . I respect your way of explanation but the way you are trolling other physics teacher may be a little bit polite. Yes, they shouldn't use it as a trick or tactics by dancing 😂.agree

I suddenly watched this video as I am an engineer so compelled to write about it .Current is not vector why- Because it’s derived from drifted electrons flow carrying charges per unit time like water or liquid flow .a water flow can not be termed as vector quantity it’s just like that. Don’t confuse students. Your concept is not clear first clear your concept.

Regarding area ,it is not like we choose whether there is direction or not , to define an area properly the orientation of area is important, that means to define area completely it is not a choice but a compulsion to have a direction,so it is a vector and current doesn't have direction but have a sense
