From ~3:58: If I know well, electric polarization is a shift of positive and negative electric charge in opposite directions within an insulator, or dielectric, and it occurs when an electric field distorts the electron cloud around positive atomic nuclei, so with metal you get maybe charge sharing (I don't know the english name of it) but not polarization...

1. When rubbing a glass rod with a cloth, why don't the excess electrons move into the person holding the object? And why don't those electrons then move from the person and into the positively charged object? 2. What determines which object gains electrons and which object loses electrons? 3. When people build up a static charge, how can they retain the charge to get shocked by something metallic? Why is the charge not immediately discharged into the ground?
@michaelsommers23568 жыл бұрын
1. Because glass and cloth are not good conductors (that is, they are insulators), which means that current does not flow easily, or at all, in them. 2. The nature of the material. Some elements give up electrons easily, others grab them easily. 3. Because they are isolated by insulators. That is, there is no conductor connecting them to something else that can take or give up electrons.
@saeedbaig42498 жыл бұрын
3. By insulators, do u refer to the floor and shoes and socks and stuff? So if I were to stand, barefoot, on bare Earth, would I be incapable of building up a static charge?
@stellarfirefly8 жыл бұрын
Sideeq Mohammad I'm rather wondering that myself. I can understand being insulated by, e.g. soles of shoes. But then why can one discharge into a doorknob that is insulated from the ground by about half of a door, but not discharge into the wooden door itself?
@saeedbaig42498 жыл бұрын
stellarfirefly I'm assuming because wood is a poor conductor. Charge can easily flow from your skin to the metal doorknob. But I'm not an expert on this stuff.

For "charged by contact" and polarization, I thought that if an electron was already "linked" to a proton it wouldn't be drawn to anything else.. The electrons go towards the area with more protons because the bigger positive charge breaks that attraction it had with that sole proton it was originally linked to? Great video though I would have liked to have it all explain from this point as it becomes even more fascinating.

thank you Crash courses team for all your efforts. please consider that not all the people watching videos on a specific topic are professionals in that field. I think that most of the people watching the videos on physics, for example, are from other back ground who are keen to expand their knowledge in physics. Also, do not forget that there are many people that are watching your videos do not speak english as their first language, despite the fact that they may completed a PhD degree in their speciality in a country which use english as first language i.e. their english is quite good. Therefore, please speak at slower pace so we can understand you from language and scientific perspetives. Sometimes I can easily notice that the presenters in your channel can not catch their breath.

The division by a square represents the lines of force as though they were taken as an integrated surface a particular distance from the centre of their emission, that is to say, the surface of an imaginary sphere. All equations where the strength of a force between two particles can be visualised in this way, and the strength of the force is the reciprocal of the distance between them.
