If we pass some current say 1A through a resistor, we get 1A current out of it. But the function of a resistor is to reduce the current right? Please clarify if I have misunderstood the concept.

Expert Answer:

A resistor works on the principle of Ohm's law.
 
When a cell/battery supplies a voltage V across the circuit, then depending on the resistance connected in the circuit, a particular current flows across the circuit.
 
Hence, if 1 A current flows, then the resistor resists whatever excess current above 1 A exists in the circuit.
