Circuit Analysis Question

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.

2. BobGuest

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?

4. Andrew HolmeGuest

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.

5. Andrew HolmeGuest

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

yes

7. Rich GriseGuest

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

Cheers!
