A conductor consists of Electrons & Neutrons. Nucleus. Nucleus is stationary which is the combination of Protons & Neutrons. When the conductor is excited under electricity, all the free valence electrons move in one direction and opposite to that current flows which is of positively charged. But actually positive charge was carried by nucleus which is stationary. Then how movement of current takes place,i.e positive with nucleus stationary ?

actually some of your assumptions are wrong...consider a conductor ..a copper wire made of millions of atoms... the electrons (not just valence but all) of each atom do move when the current is made to pass through the wire but when we say the electron is moving it actually moves in the circular radii of the orbit around nucleus so the electrons just shift to the diametrically opposite point of the orbit and that is notified as motion of electrons..... (some thing like longitudinal wave).... and nucleus NEVER MOVES i mean also the proton...if the proton moves it would be a miracle leading to a major source of energy...

Current is all about positive charge. We consider electron as negative charge and proton as positive charge. Since the proton is stationary, How positive charge is getting transferred from one point to other. which we actually consider as current.
