Hello.

When capacitor is charged, we normally say + plate is positively charged while - plate is negative charged. Charge of the - plate should be electron but what are there in + plate? Is it hole like semiconductor?

the electrons from the positive side actually goes to the native side
that means that the positive side looses electrons.
it is actually the same idea.

Electrons are actually going from negative to positive right?

So you mean when cap is charged negative side is occupied with electrons while positive side has no electron? I don't think it is right picture since electron has no point of potential reference within cap.

The positive charge is actually caused by the protons in the atoms that lose an electron, but the protons and atoms don't move (other than from thermal vibration), of course.

Thanks. It makes me clear.

Can I ask one more question? Does we normally say holes in metal? I thought the metal has fully occupied valence band and partial occupation in conductor band so no need to talk about hole in metal..
