Oh, and just by the way,  I remember when metal film resistors first
appeared on the market. They replaced carbon resistors which weren't
very reliable at all and quite given to going higher in value.

Anyway, some co-workers of the time were quite interested in seeing
how good these new metal film resistors were.

So they overloaded these resistors so much they were eventually just a
smoking black ruin. However these darn resistors still measured
exactly the same as when they were undamaged.

Metal film resistors are pretty tough guys!
