    Solution Preview

    This is a problem in parallel and series resistors.

    You need two equations:
    1. Resistors in series (s): Requiv = R1 + R2
    2. Resistors in parallel (||): 1/Requiv = 1/R1 + 1/R2 = (R1*R2)/(R1+R2)

    The original circuit in text form (omitting units):

    5k s {30k || [22.25k s ...

    Solution Summary

    The solution gives step-by-step instructions for finding equivalent resistance of a complex series/parallel circuit of pure resistance. Circuit notation is given solely in text format. No drawings are provided.
