What term describes the movement of electrons along a conductor?

• A. Current
• B. Electricity
• C. Power
• D. Voltage

Answer: (B)

The movement of electrons along a conductor is called electric current. It describes the rate at which electric charge passes a point in a circuit and is measured in amperes. Electricity is the broader phenomenon that includes charges, energy, and fields, not a specific rate of flow. Voltage is the potential difference that pushes charges through the conductor, and power is the rate at which energy is transferred, equal to voltage times current. A helpful link is Ohm’s law, which shows how current relates to voltage and resistance: I = V/R. Also note that electrons actually move opposite to the defined direction of current, which is the flow of positive charges.
