All about current flow: electron flow vs conventional flow

The flow of current can be described in two ways: conventional flow and electron flow. These two descriptions represent the direction of current flow in a circuit and are used in different contexts. Conventional Flow: Direction: In conventional flow, current is considered to flow from the positive terminal of a voltage source (such as a battery) to the negative terminal. This is the historical convention established before the discovery of the electron and is still widely used in circuit analysis and electrical engineering. Symbolic Representation: The arrow in circuit diagrams points in the direction of conventional current flow, indicating the path from positive to negative. Electron Flow: Direction: In electron flow, current is considered to be the movement of electrons, which are negatively charged particles. Electrons actually move from the negative terminal of a voltage source to the positive terminal, in the opposite direction of conventional flow. Symbolic Representation: The arrow in diagrams shows electron flow points from the negative to the positive terminal. To understand the technical aspect of both flows, it's crucial to know the behavior of electrons in a circuit:
