What is the impact of increasing resistance in a circuit with constant voltage?

In a circuit where the voltage is held constant, increasing the resistance will result in a decrease in current. This relationship is defined by Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R). Rewritten, this can be shown as I = V/R.

When resistance (R) increases while voltage (V) remains constant, the result is a decrease in current (I). This inverse relationship highlights that as you make it more difficult for the current to flow (by increasing resistance), the amount of current flowing through the circuit decreases.

Thus, in scenarios where only resistance varies while maintaining a constant voltage, the current in the circuit will diminish as resistance increases. This fundamental principle is essential in circuit design and analysis, ensuring that engineers can predict how changes to one component of a circuit will affect its overall performance.
