I would like to measure the temperature of some wire I am using while at high current.
I am using the copper resistance and a high accuracy voltmeter.
I am avoiding using any connectors and connecting my probes directly to the wire
but I have an issue where as I watch my voltmeter (at a stable current) the voltage is slowely decreasing.
If the wire was heating the voltage across it would go up, not down... im confused.
Any ideas anyone?
