We know that all charges are caused by excess or shortage if electrons. Since electrons are negatively charged, it makes sense seeing negative charges in motion which we usually see in electrostatics. But how does positive charge move? I mean when we have a sphere that is positively charged,we say that the positive charges rearrange themselves in such a way that they reside at the surface of the sphere. But how can positive charges even move? What moves are the electrons and positive charge simply means electrons have left that place.So i don't understand this movement of positive charges intuitively. Also in circuit, we mention current is the flow of positive charge, when the scientists of that era came up with this definition, what particle did they mean by this positive charge? Was that the flow of proton as positive charge?
This doubt has been a hindrance in me feeling static electricity though i can solve problems using formulas but using formulas without understanding the concept doesn't help me much.
