3.7 A silver wire has a resistance of 2.1 Ω at 27.5 °C, and a resistance of 2.7 Ω at 100 °C. Determine the temperature coefficient of resistivity of silver.
Answers (1)
Given,
;
;
We know,
2.7 = 2.1[1 + (100 - 27.5) ]
= (2.7 - 2.1) / 2.1(100 -27.5)
= 0.0039
Hence, Temperature Coefficient of silver wire is 0.0039
