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.

I must have watched it like 5 times now and every time I'm at the end I am certain I don't know what it was about. I think it is the lack of really tangible examples and the shear pace and scope of science covered during that super fast pace that limits comprehension and retention of the material. Pointless

At 3: 25, why does the contact between the positive and the neutral rod transfers electrons? Aren't they glass rods, and thus, insulators?
And if there is a reason for electrons to flow that way, why don't they travel through me and get -grounded-, thus, neutralizing the charges?

What causes static charge voltage be so high that you can be shocked when you touch a water tap. I mean, the charge imbalance you carry must be a very little faction of a Coulomb.
More in general, can you say something about why static voltages is so high in many cases?

It is easy to understand and you could learn about the positive and negative charges, charges of the same sign repel each other, while charges of a different sign attract each other; that is, the electrostatic forces between charges of the same sign

what are the odds of getting a mini crash course series on electricity alone? There is so much content, from basic theory, AC vs DC, current, motors / generators, different kinds of load on a circuit, different electrical components ect.

I have a question that I hope someone can answer
At 2: 43
That cloth is negatively charged since electrons move from the rod to the cloth
But why didn't electrons move from the cloth to the rod?

Can you not move along so quickly? It is impossible to gather all of the information and process it when you explain it all in such a hurry

I love how Crash Course videos explain a weeks of physics lectures in under 10 minutes in a way that we can understand. Thank you!
