Final answer:
The direction of current flow at any given moment is described by resistance in an electric circuit, especially in the case of alternating current.
Explanation:
Resistance is the term used to describe the opposition to the flow of electric current in a circuit. In the case of alternating current (AC), the direction of current flow is continually alternating due to the changing potential difference across the resistor.
