Which term describes the flow of electrons?

Which term describes the flow of electrons?

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

Answer: (C)

Flow of electrons in a conductor is described by electric current. Current tells you how much charge passes a point per second, and in circuits it’s measured in amperes. In metals, electrons drift, producing this charge flow. Voltage is the driving potential difference that pushes charges, but it isn’t the flow itself. Charge refers to the amount of electric property carried, not the motion, and power describes how quickly energy is transferred (P = IV). Note that electron flow is opposite to the conventional current direction, but the term current still describes the flow of charge.
