What is an Electric Field? (Physics - Electricity)

Показать описание

This physics lecture will provide you with a clear understanding of what is an electric field.

First, we define the word “Field” and give a few examples of various fields. Once we know clearly what a field is, it becomes easier to refocus on “electric fields”.

And for that, we will create one:
By pinning a charge in space, we realize that the well-known +/+ repulsion and +/- attraction can be described in terms of the effect of an electric field. The video builds from there and the nature of an electric field becomes very clear to the viewer.

If you are not sure what are electric fields, it is very probable you have also trouble with understanding electricity. It is for you that I made this video: Once you get what an electric field is, your study of electrical sciences will appear significantly easier! Understanding what an electric field really is will give you wings in your study of electricity!

The level required to fully enjoy the content of this physics documentary is high school (Grade 9 through 12)

This physics lesson is a part of a 3h online course that discuss electric charges (electrostatics) , electric forces and electric fields and provides many training exercises to crystallize your knowledge and see how it applies in real life. If you found this useful, you will find the course indispensable! And, guess what? It’s available right now!

Course: “Electricty, The Basics”

This video is produced and presented by Edouard Reny, Ph.D. in materials sciences and private tutor in Physics.

During my graduation I was able to solve equations but never could understand the concepts behind them so clearly as I have watching this video, thanks professor.

Especially for enginering students who get lost in maths of phyics, this video is really usefeul to understand fundamental terms. Thanks a lot

I am a high-school student from India
I am always curious to learn what is the concept behind
Your videoes always help me
Thank you sir

The animation at first and then the explanation on board helped a lot. This video gave me the idea of the basics of this concept. Thank you🙏🙏

All your videos describes your deep understanding for basics

I cant explain how awesome this video was. Thank u so much sir.

I have a doubt (I know I am 3 years late).
On Wikipedia, I read the following definition of electric field:-
"...defined at each point in space as the FORCE PER UNIT CHARGE that would be experienced by a vanishingly small test charge of held stationary at that point".

What does The Force Per Unit Charge mean here? Like what is it refering to, the source or the test charge and what does it mean??

Also the video was awfully nice and comprehensible. Thanks.

Thank you for this explanation, no one could visualize this abstract idea like you just did! Helps so much!

I always said if you understand something logicaly and intuatively to trully be informed by it, its then that it can look easy and sink in, and you do that briliantly sir, logic and principles must be explained before the math and only then the math wont look wierd and complicated.
Keep it that way

Sir
Hats off🙏🏻
Simply amazing, im 28 and till now was not really clear about the concept of what really the electric field is
But this video of yours helped me alot
Will surely watch this video 2 3 times more so that i can understand more about e fields
Thankyuuu so much sir ❤
Love from your new Indian subscriber🤗
