It was obvious to me for all the reasons you mention, that's why I went
and looked at the data*** yesterday to see. However, it might not
have been obvious to the OP (and it likely wasn't) given his post and
his nym. I didn't feel the need to jump in and make a scene though. I
figured you'd catch it or someone else would. No biggy. Certainly not
like the sacrilege of misappropriating the word "current" in S.E.B, I
see.

I don't want an apology for pointing out my mistakes, I want one for
cussing me out after I pointed out your mistake. I admit my mistake yet
again, when will it be enough for you?

I guess that's only as long as I don't say "current" when I really mean
"power".

I think I knew it 25 or 30 years ago.

At least we can agree on something.

Your falacious analogy aside, the end result is a smoked part. The same
as when you put too much current thru it. I defy you to tell the
difference in a post-mortem exam.

Other than your inability to apologize for cussing someone out and
calling them names.

Too bad you didn't "wake up" to your "trypo" until after cussing me out.
