Electric circuits- HELP!

    electric circuits-- HELP!

    Ok, so I have a quiz on this material tomorrow and I am thoroughly confused. My teacher gave us review problems and I keep getting them wrong. One of them was:
    Answer the below questions for a case in which three resitors are positioned in a series with a battery and each of the three resistors is 9 K ohms. The battery potential difference is 1625 mV.
    (a) What is the equivalent resistance of the circuit?

    Please help me figure out where to start... I am so confused.

    -Olivia

    First you should review what to do with resisters in a series or parallel. If in a series do you add them or do you add the inverse? There should be something in your book that mentions what to do.
