I tried to measure resistance of 332k Ω while dipping in liquid Nitrogen (cryogenic temperature) I got the resistance value near about 458k Ω, doesn't it contradicting "Resistance should increase and decrease with increase and decrease respectively with surrounding temperature"?

    \$\begingroup\$ It's just a trend that resistance increases with temperature. Otherwise things like NTCs would not exist. I don't know what regular resistor material decreases resistance as temperature increases though. You need to provide us with the resistor information. \$\endgroup\$ – DKNguyen Feb 4 at 18:48

  • \$\begingroup\$ @learner you might have to correct for a lot of effects there. I don't trust a resistance measurement when there's high temperature differences involved – Seebeck effect vs low measurement currents. \$\endgroup\$ – Marcus Müller Feb 28 at 16:21
