The flow (rate of flow) of electrons in a conductor is called what?

• A. Electrical current
• B. Voltage
• C. Resistance
• D. Capacitance

Answer: (A)

Electric current is the rate at which electric charges flow through a conductor. It describes how much charge passes a given point each second, and is measured in amperes (1 ampere = 1 coulomb per second). In a metal wire, this flow is essentially the movement of electrons, though we often refer to the current as a general flow of charge. Voltage, the driving force behind this motion, is the electric potential difference that pushes charges through the conductor. Resistance is what restricts current for a given voltage, depending on the material and its dimensions. Capacitance is a property that tells us how much charge a device can store for a given voltage, not the ongoing flow of charge.
