Question

At what temperature would the resistance of a copper conductor be double its resistance at 0°C ? Given ∞ for copper = 3.9 x 10⁻³ °C⁻¹
(A) 256.4°C
(B) 512.8°C
(C) 100°C
(D) 256.4 K

Answer 1

At 512.8°C temperature would the resistance of a copper conductor be double its resistance at 0°C

Given ∞ for copper = 3.9 x 10⁻³ °C⁻¹ and it is applicable for the student to apply the given values in the formula and get right answer for your question with no risk and trouble of it.
