Quote: “We can see from our definition that the positive plate in Fig. 23-1 is at a higher potential than the negative plate..." I saw this statement in a book. May I know how to calculate the potential of a charged plate?

In what way can we quantize the field? :confused:

Hmm...If I am not wrong, energy should be brought by some force carrier particle. So, besides photon, are there any other massless particle that made up electric field?

Recently I am reading about electirc and electromagnet. I found electric field and the field line a bit confusing. What forms the field, or the field line? Is it photon? Secondly, why must electron orbit around proton, and not proton orbit the electron? :confused: Thanks in avanced.

Talking about lightning, is it possible for human to simulate lightining in order to generate electricity?

That's interesting. Can you explain more about magnetohydrodynamics if you don't mind?

In this modern era, there are many type of power plant, from hydro electric power plant to nuclear fission power plant or even nuclear fussion(still in research). However, besides solar power plant, most power plant require movement of turbin to generate electricity. I think, that the speed of...
