A(n)_________ is the flow of electricity along a conductor

Atom
Electrical field
Electric current
Voltage

The correct answer is: Electric current

The term that accurately describes the flow of electricity along a conductor is "electric current." This concept refers to the movement of electric charges through a material, typically measured in amperes. Electric current occurs when there is a potential difference (voltage) across the conductor that causes electrons to flow. When discussing other terms, an "atom" refers to the basic unit of matter and does not specifically pertain to electricity. An "electric field" describes the influence that charged objects exert on one another but does not define the actual flow of electricity. "Voltage," while related to electric current as it provides the necessary potential for current to flow, specifically measures the difference in electric potential between two points and is not a direct description of the flow itself. Thus, "electric current" is the most fitting term for the flow of electricity along a conductor.
