    Does it matter where one places a resistor on a circuit with a battery
    and LED. I mean I understand that charge flows from negative to
    positive, so if I place the resistor after the LED, will the resistor
    still protect the LED or do I need to put the resistor before the LED?

    It makes no difference. The resistor simply needs to be in series with the LED.
    Whether it's on the positive or negative 'side' makes no odds.
