Resistor Question

[Jack00]

Theres a resistor I used in the past but I don't know what its
called. It has a red body with no bands on it ie no lines and it
stays cool in high power applications. Does anyone know what it is
called? Thanks

It's probably called a "Power Resistor".

If Dave called it right, it's more brown than red.
It's also visibly hollow.
Anything look familiar?

Might it be one of these?

Lots of them in this photo.
These were some of the earliest resistors, and the body color as well
as the end colors and dots were the color code. It looks like they
were all hand painted back then.... what a monotonous job!

Look at this chart for the color codes on them.

If I'm right, the red one on the picture would be a 250 ohm.

If you're speaking of power resistors, they are usually brown, but can
be other colors and normally have the ohms and wattage written on them
in text, although some of them seemed to lose their lettering from
heat. These buggers can get quite hot, and will burn your fingers.
These are wirewound, rather than the smaller ones being a carbon type.

Good grief ! 40+ years ago I used to have a copy of that page pinned to
the wall behind the bench to remind me of the value of the colours !
