Which statement best describes conventional current flow?

The statement that best describes conventional current flow is that it flows from positive to negative. This concept stems from historical conventions established before the discovery of electrons. At that time, it was assumed that electric charge was carried by a positive charge that moved from a higher potential (positive terminal) to a lower potential (negative terminal).

In practical applications, this means that when considering circuit diagrams and analysis, engineers and technicians use the idea of conventional current to describe the flow of charge. This helps in understanding how circuits are designed, analyzed, and explained, even though in reality, electrons, which are negatively charged, flow from negative to positive.

Understanding conventional current flow is essential for interpreting schematic diagrams and working with electrical components, which usually assume this positive-to-negative flow when specifying the direction of current in analyses and calculations.
