Physics - E&M: Ch 36.1 The Electric Field Understood (3 of 17)What is Electric Field of a Charge?

In this video I will explain the electric field produced by a single point charge. And I will find F=? of a small test charge placed within this electric field.

Next video in this series can be seen at:

1/4pi * 1/R^2 = 1/4piR^2 also shows that the electric field intensity is equally distributed over the surface of a sphere which area increases over increasing R, thus the flux density and E-intensity decreases, and the surface integral of E on the sphere for all R remains the same.

Thank you very much sir. I didn't realize the lecture is ended. I like your teaching

[Sofialovesmath]

I am eternally grateful for your efforts!

My exam is in 1 week; I am so glad I found your channel.

so when we use E=kQ/r^2, the size of the test charge doesnt matter at all?

Is an electric field made of microscopic electric dipoles which surround electric monopole at the centre of a charge. These electric dipoles could join together like iron filling along magnetic field lines and present same pole to the incoming electric field which is at the centre of charge. An electron has negative & position positive monopole at their respective centres.

Hi, I always cherish your videos. In this particular case, Dont you think if you have explained E=F/q then instead of Electric field formula you wrote straightaway, you need to use that Coulomb force formula and then divide by q to get EF formula ? I understand this video was not about deriving EF formula but always good to have in context with Coulomb force if you already discussed. Thats my 2cents only, otherwise I watch most of your videos and gets lots of information. Thanks
