Final answer:
Electric current is the charge that passes through a conductor per unit time. It is the flow of electrons through a material.
Step-by-step explanation:
Electric current is the charge that passes through a conductor per unit time. It is the flow of electrons through a material. So, the correct option that best describes an electrical current is C) Flow of electrons. Voltage refers to the potential difference that drives the flow of current, resistance is the property of materials to resist the passage of electric current, and static charge refers to the buildup of an electric charge on the surface of an object.
