    1/R = 1/R1+ 1/R2 - Parallel Resistors



    3. I thought it was 1048 but that was just because I thought 542*2 I really had no idea how to work this

    Re: Resistors

    Resistors in Rectabgle 3 are in parallel with that in rectangle 2 and the parallel combination are in series with rectangle 1:

    RAB = [(R + RL) // R] + R = RL = 542

    SO,

    [(R + 542) * R / (R + R +542)] + R = 542
