A higher resistance in a circuit typically leads to a decrease in current flow. According to Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), increasing the resistance while keeping the voltage constant will result in a lower current. This relationship illustrates that if resistance increases, the amount of current able to flow through the circuit decreases.

In practical terms, this means that when devices or components in a circuit possess higher resistance, they impede the movement of electric charge. Consequently, fewer electrons are able to traverse the circuit per unit of time, thereby reducing the overall current. Understanding this principle is essential for designing circuits, as it affects how devices operate based on their resistance values.
