At 65.7K temperature is the resistance 2 ohms.
A conductor's resistance is influenced by its temperature, and a conductor's initial resistance and temperature change are directly inversely correlated. It has been noted that a conductor's resistance increases as temperature rises.
i.e., ΔR ∝ R₀ΔT
R is the temperature coefficient of resistance and T is the temperature.
⇒ R - R₀ =R₀αΔT
⇒ R = R₀(1 + αΔT)
R0 = starting resistance in this case = 1.25
0.00375°C is the temperature coefficient.
2 = 1.25[1 + 0.00375(0-[tex]T_{f}[/tex])]
2 = 1.25 + 1.25× 0.00375(0-[tex]T_{f}[/tex])
0.75 = 0.0046875(0-[tex]T_{f}[/tex])
65.7K = [tex]T_{f}[/tex]
Therefore, at 65.7K temperature is the resistance 2 ohms.
