Scalar field and Vector field | Physics video in HINDI | EduPoint

In this Physics video lecture in Hindi we talked about scalar field and vector field. When we draw a function for a scalar quantity (e.g. temperature ) associated with a point in terms of its coordinates, the function is called a scalar field. And, if a function depicting a vector quantity (e.g. electric field intensity ) at a point in terms of its coordinates, the function is called a vector field. The study of field theory is indispensable for a student of B.Sc. , M.Sc. , B.Tech. or M.Tech.

[Adityakumar-wffp]

Sir complete all the chapters of bsc physics, u r great and I love all the videos of yours

[harmann]

Sir, only you can provide best lectures for bsc physics on YouTube. You are our only hope sir.

[sarminnahar]

You’ve used Very brilliant technic. Your teaching proficiency along with the correlation of those smart computer contents make the topic easier for me.I am new on vector and calculus so your video was worth while in this regard...I am Bangladeshi so the language I use is obviously Bangla but as I learned Hindi from my very childhood by myself, your video did not show any difficulties for me to understand. High appreciation and love from Bangladesh 🇧🇩❤🇮🇳

[somnil]

Sir this lesson was written so clumsily in book but you made it so good, I am watching your lessons from 12 till 1st year engineering, thank you so much🙏

[shovanray]

You are the pioneer of my passionated learning in Physics

[deepikadas]

Sir plz complete bsc physics (with mathematical physics). Our physics lecturer send us your videos to see. Your videos are great👍👏. Plz continue it.

[fantastic]

This channel has awesome explanation that's why I am watching it since 9th class now I am in btech first year

[amitnayak]

Your channel is great, No one can explain me with this smoothness and easy to understandable....and now i am able to relate vactor calculus with different existing applications in nature....

[chempoint]

I thought I cant start bsc without a physical teacher butt now I can tq sir

[kamalsubba]

One of the best educational channel sir ....👍👍👍

scalar field ke har point par function has a value but doesn't have direction (ex. temperature at points in x, y, z space is a scalar field function)

whereas in vector field every point in x, y, z space has a value as well as direction of that value (ex. electric field in x, y, z space)

gradient points towards the max change of a function from an initial point and the magnitude represents the how big/small the change is

therefore, gradient of a scalar function in 3-dimensional space is a vector function in 3-D space where at each point this vector gradient function points towards the max change of the scalar 3-D function and the magnitude of change is represented by the size of arrow

hence, gradient of scalar function is defined and is a vector function

gradient of function = change of fxn in x/dx x^+ change in fxn in y/dy y^ + change in fxn in z/dz z^

vaise hi potential in 3-D space is a scalar field, somewhere it is high and somewhere it is low, and gradient of potential i.e electric field is a vector field in 3-D space

since electric field lines/vectors at every point points from higher potential to lower potential hence, a negative sign is there in gradient

i.e E=-delV

now, why is gradient of vector field is not defined, change of vectors is also possible by subtracting vectors?

note- x, y, z need not be coordinates they can be parameters on which the function scalar/vector depends.

[riteshpandey]

Thank you sir
You are my favorite teacher

[ajaysingh-qely]

sir aapke jaisa lecturer pura india me kahi nhi milenge mai aapse milna chata hu sir ji

[PappuKumar-fdgd]

Sir, you are great itna acha to IIT m v nhi smjh aata

[aftabKhan-jgcc]

very very unique video..soo helpful for cocept clearing ..superb ...

[sachingurjar]

Sir thank 🙏💕 you so much such btaau to aapki taarif karne ke liye word km hai sir thank you thank you SO much pr sir please aapse deeply request hai ki hm jaise bachho ke liye pura B. Sc ki EMT course ki vedio bnaye aap bahut accha explain karte hai aur saare concept bhi btate ho sach mai aap physics ki feel de jaate ho again thanx sir

[atulkulkarni]

Really amazing... Previously whenever I was use to listen the scalar field and vector field I just understood the area under the influence... But you have amazingly explain the formation of function for scalar as well as tricky vector field.... Thank you for such wonderful video.... Got superb insight....

[COLLEGEMATHEMATICS-dqcj]

best explanation sir very best realy enjoy this video lecture thnkyxx sir

[piyushmitra]

Sir, I follow your videos from class 12 ..and now I am going to be a bsc in physics...so I need more videos like ...this .I mean all topics of bsc physics syllabus...🙇
