Which statement is true about the flow of electrons in conventional current?

The statement that conventional current flows from positive terminals to negative terminals is indeed true. This concept is rooted in historical practices established before the discovery of the electron. At that time, scientists assumed current flowed from positive to negative due to a lack of knowledge about the actual particles involved.

In conventional current flow, the direction is defined in relation to the positive charge movement. Therefore, when we refer to current in circuits, we acknowledge this convention, despite electrons, which carry a negative charge, actually moving in the opposite direction—from the negative terminal to the positive terminal.

This convention is critical in understanding circuit designs, electrical engineering, and analyzing electrical systems, as it allows consistency and standardization across various applications. It is important to note that while it may seem counterintuitive, the adherence to this convention is largely historical and helps maintain continuity in the study of electrical phenomena.
