OK, I left something out (saying to use 6V, or clarifying what "big

Mark,

If I may interject here ... The discussion was about connecting 6V
lamps to a 12V supply. As you said, you didn't mention anything about
changing the supply to 6V.


The discussion was about 6V lamps, "12V" was a later addition,


No, it was not -- the 12V is in the ORIGINAL POST.

which I
posted an ALTERNATIVE to. Sorry for not making things clearer.

I didn't say 6V because it was ALREADY 6V,


Wrong again. The ORIGINAL POST was complaining that the subject had been
explained so poorly in school that the OP's daughter thought she needed a 12V
supply to power two 6V lamps.

I said that was fine, if they were wired in series.

You said "or in parallel, if the power supply is big enough."

as appropriate for a 6V
lamp (perhaps I underestimated people's lack of knowledge).


The only lack of knowledge apparent here is yours. It's not quite clear
whether that lack is in the difference between series and parallel wiring, or
in reading comprehension.

As I did
mention, it would have been better to have included that information
anyway. I apologize for the mistake I did make, just not for the one I
didn't.


You still haven't figured out which mistake you really did make, and I'm still
waiting for your apology for accusing me of having put things into your post.

It's perfectly reasonable for Doug to
assume you were still talking about a 12V supply. End of story.

Respectful regards,

Mark
