    I am taking an electronic circuit analysis class via correspondence and one
    of the questions on the homework assignment has the following statement
    concerning two identical diodes connected in a circuit:

    "They are connected in series, back to back."

    Am I to assume they mean anode-to-anode or cathode-to-cathode instead of
    both oriented identically (i.e. cathode-to-anode)?

    Thanks for any clarification. Unfortunately there are no similar examples to
    compare to in the textbook and the question in question does not include a
    diagram.

    I think you're correct. To me, back-to-back means same-to-same --
    anode-to-anode or cathode-to-cathode.

    Why not post the entire question, then perhaps we can come up with
    reasonable conclusions?

    Yes, that is what back-to-back means.

    Are they zener diodes? If so, then it would make sense for them to be
    in series. Normal signal diodes would be connected in parallel,
    back-to-back.

    To clarify: Parallel back-to-back means the opposite i.e. anode to
    cathode.

    Technically, that's called "antiparallel" to distinguish it from
    back-to-back series.

    Cheers!
