What is defined as the movement of electrons along a conductor?

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

Answer: (A)

The movement of electrons along a conductor is current. Current is the rate at which electric charge passes a point in a circuit, measured in amperes. In metals, electrons drift as they move, but we describe the flow of charge by current—the amount of charge crossing a section per second. Voltage is the driving potential difference that pushes the charges, while power is how quickly energy is transferred (voltage times current). So the term that specifically captures the actual flow of electrons along the conductor is current.
