As resistance increases, current decreases if the power supply is constant
As the resistance in a circuit increases, the current in the circuit decreases, as long as the power supply is constant. This happens as resistance is the opposition to current, so the higher the resistance, the more current is restricted, therefore it decreases.
Here is an example of this in action in a real scenario:
