Circuit Analysis Question

Apr 21, 2005 6 Replies

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.

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.

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?

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