The Battery Circuit !!! Electron Flow Vs. Conventional

In Physics class today, we discussed about two things that seem like the exact same things, but in fact they are the direct opposite-conventional current flow and electron flow.

Electron flow is simply the movement of electrons through a circuit, and conventional current is the movement of the positive charge. As you can see from the following diagram of a battery circuit, it has a battery (cell), an open switch, a load (light bulb) and the arrows showing the directions of the movements. In conventional current flow, it is said to be that the electricity moves from the positive electrode of the cell through the circuit to the negative end ( +----> -).

For electron flow, the electrons are moving from the negative end through the circuit to the positive side (- -----> +).
