Question

A silver wire has a resistance of 3.00 \Omega at 30.0^{\circ}C. Determine its resistance (in \Omega) at 430^{\circ}C. The temperature coefficient of resistivity for silver wire is $3.80 \times 10^{-3} (^{\circ}C)^{-1}$. (Assume that the temperature coefficient of resistivity was measured using the reference temperature 20^{\circ}C.)

Step 1

The change in temperature is given by: ΔT = T2 - T1 where T2 is the final temperature (430°C) and T1 is the initial temperature (30.0°C). ΔT = 430°C - 30.0°C ΔT = 400.0°C Show more…
