I discovered Wikipedia in February 2004, and was delighted with what I found. I am learning how to use these excellent tools and, in the process, trying to make useful contributions to topics where I have some expertise.
I am greatly impressed with the power and potential of a collaborative encyclopedia project. I am proud to be able to make a contribution.
some things to do:
despite all that there is in here, there are some important design insights still missing
in the transformer article there could usefully be a section on unintended or accidental transformers
in the foldback current limit article
