What happens to the flow of electrons when resistance increases?

When resistance in a circuit increases, the flow of electrons, which can be understood as electric current, decreases. This relationship is described by Ohm's Law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. The formula is I = V/R. Therefore, if the resistance goes up while the voltage remains constant, the current must decrease.

It's important to understand that this principle is fundamental in electronics and electrical engineering. Increased resistance could be due to various factors, such as the material of the conductor, temperature, or physical dimensions, which all affect how easily electrons can flow through a circuit.

The other options do not align with this fundamental principle. An increase in resistance does not result in an increase in current, nor does it mean that current remains the same or fluctuates; it consistently leads to a decrease in current under stable voltage conditions.
