Current flows from positive to negative.

Current flows from positive to negative.

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

Answer: (B)

The main idea here is the convention used for defining current direction. In conventional current, current is defined as the flow of positive charge from the higher potential (positive terminal) toward the lower potential (negative terminal). This historical convention is what engineers and circuit theorists use when analyzing circuits, so saying that current flows from positive to negative matches that standard definition. Keep in mind that in actual metal conductors, the charge carriers are electrons, which are negatively charged and move from negative to positive. That movement is opposite the conventional current direction, which is why you’ll hear that actual particle motion is opposite to the current direction. Ohm’s law and Kirchhoff’s laws all rely on the same conventional current direction to set up equations (I = V/R, and current flow into and out of junctions), so the statement aligns with how these tools are applied in circuit analysis.
