What is the impact of circuit resistance on current flow according to Ohm's law?

According to Ohm's law, the relationship between voltage (V), current (I), and resistance (R) is described by the equation V = I × R. From this equation, it becomes evident that if the resistance in a circuit is increased, the current will decrease, provided that the voltage remains constant. This is due to the fact that resistance opposes the flow of electric current.

When resistance is high, the same voltage will result in a smaller amount of current flowing through the circuit. Therefore, the correct assertion is that higher resistance decreases current. This concept is fundamental in electrical engineering and physics, emphasizing that control over resistance can lead to manipulation of current flow within an electrical system.
