Keeping this in consideration, do Resistors reduce current?

In short: Resistors limit the flow of electrons, reducing current. Voltage comes about by the potential energy difference across the resistor. The mathematical answer is that a resistor is a two-terminal electric device which obeys, or you could say enforces, Ohm's law: V=IR.

how does adding resistors in series affect current? In a series resistor network the individual resistors add together to give an equivalent resistance, ( R_T ) of the series combination. The resistors in a series circuit can be interchanged without affecting the total resistance, current, or power to each resistor or the circuit.

Also to know, what happens to current when it passes through a resistor?

Electric current is carried by charge carriers, which in solids are usually electrons. If there is no resistance to flow, and a steady electric field, electrons accelerate (as any mobile thing does when subject to a steady force).

How much current can a resistor handle?

Resistor Power Rating Example No2 Calculate the maximum safe current that can pass through a 1.8KΩ resistor rated at 0.5 Watts. Again, as we know the resistors power rating and its resistance, we can now substitute these values into the standard power equation of: P = I²R.
