The current after a resistor is the exact same as it was before the resistor. ... If you now add a resistor in series into this circuit – the current of the circuit will be smaller. So yes, the resistor does reduce the current. (But the current flowing into the resistor is still the same as the current flowing out.)

Do resistors reduce amps?

A higher resistance results in a lower amperage. The resistance of a resistor is measured in ohms. A resistor works by "resisting" the flow of current through the circuit. ... Lower the circuit's amperage by adding a variable resistance device or increasing the resistance on any you already have in the circuit.

Does resistance affect amperage?

If Voltage stays the same, Amps will be inversely proportional to the Resistance. Resistance the less the flow (Amps). ... You can not force more Amps into a circuit and a component will not draw more current than it's Resistance allows.
