What happens to electron flow in a conductor when resistance increases?

When resistance in a conductor increases, the electron flow decreases due to the relationship defined by Ohm's Law, which states that voltage equals current times resistance (V = I × R). Essentially, for a given voltage, as resistance goes up, the current (which represents the flow of electrons) must decrease. This is because the increased resistance presents a larger obstacle to the movement of electrons, which limits the amount of current that can flow through the circuit.

In practical terms, this means that if you were to increase the resistance by adding more material that opposes the flow of electrons, the overall current flowing through the conductor would drop. The other options do not accurately describe the behavior of electron flow in response to increased resistance; hence, they do not align with the fundamental principles of electric circuits.
