How hot?

I squared R hot, in watts or fraction thereof. And that value should be
(somewhat) less than the maximum rating for that component.

You could be running just a few volts across a 1/8W resistor, and it may
not feel so hot to the touch, but it may be running at or above its
rated dissipation. And that's not cool, no pun intended. :-)


And besides that, it measures actual in-circuit conditions, because a
resistor is *supposed* to get hot, at least if it's doing its job...

PUNCTUATION - Apostrophe
Incorrect uses: (i) the apostrophe must not be used with a plural
where there is no possessive sense, as in ~tea's are served here~;
(ii) there is no such word as ~her's, our's, their's, your's~.

Confusions: it's = it is or it has (not 'belonging to it'); correct
uses are ~it's here~ (= it is here); ~it's gone~ (= it has gone);
but ~the dog wagged its tail~ (no apostrophe).
