What does a higher resistance indicate about current flow, assuming voltage is constant?

A higher resistance in a circuit indicates that there will be a lower current flow when voltage is held constant, based on Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), represented mathematically as I = V/R.

When resistance increases while the voltage remains the same, the denominator in the equation becomes larger. As a result, the overall value of current decreases. This is a fundamental principle in electrical engineering; higher resistance opposes the flow of current, leading to a reduction in how much current can pass through the circuit. This relationship is crucial for understanding how electrical circuits operate and how components affect current flow.

Thus, the choice indicating lower current flow is accurate because it reflects the direct relationship described by Ohm's Law, emphasizing how resistance affects current when voltage is constant.
