The resistance of a conductor at 15 ° C is 16 Ω and at 100 ° C is 20 Ω . What will be the temperature coefficient of resistance of the conductor?

Question

TestHub · Accepted Answer

16 = R 0 1 + α 15 - T o 20 = R 0 1 + α 100 - T 0 Assuming T o = 0 ° C , as a general convention. ⇒ 16 20 = 1 + α × 15 1 + α × 100 ⇒ α = 0 . 003 C ∘ - 1
