According to current flow theories, who is correct about the direction of current flow?

In current flow theories, the direction of current flow is defined based on conventional current flow, which posits that current flows from a positive to a negative terminal. Technician B adheres to this conventional theory, recognizing that this is the standard perspective on current flow used in circuit analysis and electrical engineering.

This understanding is significant because it informs how technicians diagnose and repair electrical systems. Following the correct direction of flow is critical in troubleshooting, circuit design, and understanding how components interact within a system. By correctly applying the convention of current flow, Technician B is aligning with the established standards that guide professionals in the automotive electrical field.

Conversely, Technician A may be holding to an alternate understanding or misapplication of current flow principles, leading to potential confusion or errors in diagnosing electrical issues. Thus, Technician B's alignment with standard current flow theory is essential for accurate electrical diagnostics and practice in automotive applications.
