Which term refers to the standard flow direction of current from positive to negative?

• A. Conventional Electrical Theory
• B. Electron Theory
• C. Ohm's Law
• D. Kirchhoff's Laws

Answer: (A)

The standard way we think about current direction is conventional current flow: current is treated as moving from the positive to the negative terminal. This convention was set historically before electrons were known, and it provides a consistent reference for solving circuits and applying formulas. The term that matches this idea is Conventional Electrical Theory, because it explicitly refers to using the conventional direction of current flow. Electron flow theory describes actual carrier movement from negative to positive, which is opposite to the convention. Ohm's Law and Kirchhoff's Laws are rules we apply once a current direction is chosen; they don’t define which direction that should be, they just relate voltage, current, and resistance or apply conservation in a loop.
