Homework Help: Infinite array of capacitance

  1. Nov 7, 2005 #1
    see diagram for this at

    Determine the eqivalent capacitance C between terminals X and Y of the infinite set of capacitors represented. Each capacitor has capacitance Co.
    Suggestion: imagine that that ladder is but at the line AB. and note that the capacitance of the infinite section to the right of AB is also C.

    So far what ive done is calculated the capacitance to the left of AB as three capacitors in series from x to y so its: Co/3. Now i have no idea how to finish this off. It seems like i would just be adding Co/3 "infinitly many times".

    any help on this one?
