When resistance in a circuit is increased, the current flow decreases. This relationship is governed by Ohm's Law, which states that the current (I) 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 mathematical expression for Ohm's Law is I = V/R.

As resistance increases while voltage remains constant, the current must decrease to maintain this relationship. For example, if you double the resistance while keeping the voltage the same, the current is halved. This fundamental principle is crucial for understanding how electrical circuits operate and how to design or troubleshoot them effectively.

The other options do not accurately reflect the behavior of current in response to increased resistance as defined by Ohm’s Law.
