# does a resistor slow down the flow of electrons or just let less electrons through? or is it both?

I like to have an intuitive grasp of whats happening our tutor said they 'resist' the flow of electrons but I want to understand exactly whats happening.

There is another reason why it's not possible, or at least practical, to lower the number of electrons. In this case the "resistor" should take away the particles from the flow and store them somewhere, for example by binding them on atoms. You can see the major problem here: in little time the resistor would be completely full and will stop working. Ejecting the electrons appears to be a solution, but that would interfere with the rest of the circuit and I don't think the general public would feel very excited about resistors that behave like $\beta$-emitting radioactive nuclei. ;)
