Postive to negative or the other way around?

In solid matter, only electrons are mobile (the lattice of nuclei is fixed). This means flow of electricity is ALWAYS down to movement of electrons, which is ALWAYS -ve to +ve.
In some materials it is useful to think of conduction being by holes - which are really missing electrons in the lattice (so +ve charges). But the nuclei do NOT move in this case - it is still electrons that do the moving.

In solid conductive metal, with no external forces applied, there exists a random motion of "mobile" or "free" electrons created by the thermal energy which the electrons have gained from the surrounding medium. When a metal atom contributes a free electron, it acquires a net positive charge. The population of freed electrons form a "charge-gas" or "sea of charge" which remains bound to the ion lattice by attraction, while the metal as a whole remains neutral. Metal atoms typically contribute either one or two electrons to the "sea." Free electrons can move amongst these positive ions, while the positive ions can only oscillate about their mean fixed positions. Electrons move, but the net flow of charge remains zero: given an imaginary plane through which the wire passes, the number of electrons moving from one side to the other in any period of time is exactly equal to the number passing in the opposite direction.

Depends on who you ask. Seriously.
The actual flow of electrons is from the negative pole to the positive pole. The flow of the positive potential, or "holes" is from positive to negative.
Each has an equal potential - the electron being negative and a missing electron being positive (due to the proton).
I personally rather like to think of the electron as an actual particle that flows from negative to positive.

Electrons flow from Neg to Pos

Electrons move from one spot to another. Depends on if you go by conventional theory or not if you say from a + to a - or a - to a +. Remember Voltage is electrical pressure. Amps is currant flow. Ohms is Resistance to currant flow. Static electricity is at least 40 volts. That's why a car battery will not shock you.

It is negative to positive . Use a vacuum tube preferable a power rectifier and it only will go negative to positive.

Electrons are forced into loop leaving a vacuum where they come from so they return to the point they were forced from.

neg to positive inwires and the other way arund in batteries. But i think it is a conspiracy
