One of my component suppliers gave me a power resistor for free for some reason. It is one of those ones with integrated aluminum heatsink and mechanical mounting holes. Whatever marking that was on there has long been scrubbed away.
When I measure it with the ohms range on my multimeter, the result seemed a bit inconsistent to me since the resistor is almost within the range of the resistance of the leads I am using. How should I measure it then? I don't have a multimeter capable of four-wire measurement, but will a ghetto four-wire measurement solution using a bench power supply, a Uni-T UT61D and a UT61E work? How should I arrange the two different meters for the maximum accuracy?
How do I estimate the power ratings of such a resistor?
Also what can I do with it? The leads on both ends of the resistor is millimeters thick and very hard to bend, so should I solder it to a PCB directly at all? If not how should I attach it to a PCB?
