From which charge do electrons flow?

Electrons flow from the negative charge to the positive charge. This is because electrons are negatively charged and are attracted to positive charges due to the electrostatic force. In an electrical circuit, when a potential difference is applied, typically referred to as voltage, the electrons will move towards the region of higher potential (positive) from the region of lower potential (negative).

In the context of conventional current, which is often depicted as flowing from positive to negative, it's essential to note that this representation was established before the discovery of the electron. Therefore, while conventional current moves from positive to negative, the actual movement of electrons occurs in the opposite direction, from negative to positive.

The other options do not correctly reflect the nature of electron flow. Flowing from a lower potential to a higher potential describes the movement of conventional current but not the actual flow of electrons. High amperage to low amperage refers to the flow of current due to differences in current, not the movement of electrons based on electric charge. Therefore, the correct understanding is that electrons flow from negative to positive.
