What happens to the amperage in a circuit as resistance increases?

Increases
Decreases
Remains constant
Is irrelevant

The correct answer is: Decreases

When resistance in a circuit increases, according to Ohm’s Law, which states that Voltage (V) = Current (I) x Resistance (R), the overall current (or amperage) in the circuit decreases if the voltage remains constant. This relationship highlights that an increase in resistance leads to a reduction in the amount of current flowing through the circuit. As resistance rises, the opposition to the flow of electric charge becomes stronger, resulting in less current being able to pass through the circuit components. This principle is foundational in understanding electrical circuits and their behavior regarding voltage, current, and resistance. Hence, in a scenario where you maintain a constant voltage and increase resistance, it is expected that the amperage will indeed decrease.
