The photo doesn't but in the text is states the resistor is 11mm.
My 1/4 W resistors are about 6mm long and 2mm in diameter.
The 3W resistor I quoted was 16mm long, so I'm guess it was about 1-2 watts
in it;s original form.
Thanks to all who responded. That's my guess as well, I think the initial digit "1" on the PCB might have been to denote this as a 1 watt resistor, and the 4.7 the resistance in ohms. I didn't recognise the original appearance because I guess the colour bands had burned off, and I'd never seen a naked resistor before. It's a surprise how long one can live before this happens. :-)
You great gormless wally Rodders. Is there no limit to your ignorance.
It's a carbon film resistor that has been "cooked". As it's carbon
film and the spiral is still black, it will most likely have retained
its original value. A quick prod with a DMM will enlighten.
Power resistors are made from metal, or in the case of RF dummy loads,
can be carbon, but certainly not cut in a spiral.
If you dont know what you are on about, why not just shut up Rodders??
