Physics - E&M: Ch 36.1 The Electric Field Understood (1 of 17) What is an Electric Field?

In this video I will explain what is an electric field. An electric field exerts a force on a charged place in the field, can be detected by placing a charged in the field and observing the effect on the charge. The strength of the field is proportional to the inverse of R^2 and the electric field lines have magnitude and direction.

Sir, i respect u and appreciate u very much. your each and every lecture is very much effective. I dont have any word in my dictionary to express my gratefulness to u.

[diegoarana]

If only I could just skip class and watch your videos instead. Sadly my teacher does participation points.

[jakkuwolfinsomnia]

This is so great, I love these videos you explain such a tricky subject in such an understandable way. Thank you for all your hard work I greatly appreciate it, I love to learn more

I have a question for you: I am developing the idea for a new transportation system that creates 0 pollution because it runs on gravity and the "train cart" (slides down an inclined plane at avg 255km/hr and is lifted by an electric motor at the final destination) Do you think an object moving 255km/hr+ could cause an electric field to have more energy potential and be able to create more electricity than a stationary Generator?

I think attractive electric field b/w opposite charges is due to lower space/energy density in the region b/w like charges. Repulsive electric field b/w like charges is due to higher space/energy density. It is analogous to air baloon, adding air causes push force and removing air pull force, and baloon walls move outward & inward.

Electron & proton have - & + electric field around them. Does a neutron have an electrically neutral field around it.

Hello, Professor!

Is it conceivable that charged particles, like positrons and electrons, have an impact on the expansion and contraction of space? If we were to have two points in spacetime that are contracted, the spatial symmetry between them might become perpendicular, giving rise to a repulsive force. This could offer insights into certain properties of spacetime in the presence of gravity because the non-uniform distribution of contracted space within a gravitational field might explain why an electron do not experiences a repulsive gravitational effect since gravity is a curvature of space.

I'm digging the purple and yellow combo. I have to borrow that 🤓

[AyushSoni-nkmd]

Sir, can I study from these lectures for my jee preprations

[ahmedal-ebrashy]

I kid you not sir but my self.esteem took a hit since I stopped being a regular on your channel.

[Plank]

Great video professor! Would you be able to help me understand HOW a field applies a force to a charge? I understand what the direction of the force will be based on the polarity of the charge…but not quite sure HOW that force is applied? Is it simply because thats fundamental to a field and thats all the interaction thats needed? If you could help explain conceptually that would be great…again amazing video!

[kmatsui]

just wanted to say thank you so so so much for all your videos. i have a physics midterm coming up and these videos are helping me so much.

[schifoso]

Very informative. Looking forward to the rest of your playlist.

[MS-oyvo]

Love the purple with gold bow-tie. Go Lakers!

[adnanshah]

Sir please also make lectures on whole physics

[murphdogfilms]

Just curious why is there two playlist in the Electric Field?

[amna]

The only person online I found who is passionate about emt. Very helpful for me. And concepts are clear.

[jonathansanchez]

Thank you so much for these videos; helps comprehend so much better!

[na-chan]

dayuuum I just noticed you're not gaining weight from 2013 to 2018. Keep eating healthy!!

[raghvendrasharma]

Sir please explain the concept of magnetic field and magnetism.
