What does a higher resistance in a circuit usually result in?

A higher resistance in a circuit typically results in lower current due to Ohm's Law, which states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). This relationship can be expressed by the formula I = V/R.

When resistance increases while the voltage remains constant, the current must decrease accordingly. This is because, with more opposition to the flow of current, less charge can pass through the circuit over time. As a result, in a circuit with higher resistance, the amount of current flowing is reduced, which can affect other aspects of the circuit, including power consumption.
