The vacancies left by electrons moving from the positive terminal to the negative terminal describe which type of current?

• A. Electron Flow
• B. Ion Drift
• C. Voltage Drop
• D. Conventional Current

Answer: (D)

The direction used to describe current in most circuits is based on the flow of positive charge, not the actual motion of electrons. Conventional current is defined as moving from the positive terminal toward the negative terminal. When electrons move from the positive terminal to the negative, they leave behind vacancies, or areas lacking electrons. These vacancies behave like positive charge carriers moving in the same direction as the electrons’ departure, which is from positive toward negative. That aligns with conventional current, the direction imagined for positive charges. Electron flow, in contrast, is the real movement of electrons and goes the opposite way—from negative toward positive. The other terms don’t describe a type of current in this context. So the situation described matches conventional current.
