The convention used in electrical engineering defines the direction of current flow as the movement of positive charge. This convention was established before the discovery of electrons. When electrons were discovered as the negatively charged carriers in a conductor, it was found that they actually move in the opposite direction of the conventional current flow. So, in reality, electrons move from the negative terminal to the positive terminal in a circuit. However, for simplicity and historical reasons, the conventional current flow (from positive to negative) is still widely used in circuit analysis and discussions. It's important to be aware of this convention when working with electronics and understand that it doesn't represent the actual movement of electrons.
