yup i am. im just desperate to answer this.
We are given that the resistance of the silver ware at 0 °C is 1.5 ohm
Temperature coefficient of resistance is 0.00375 ohms/° C
so for each 1° increase in temp. resistance will increase by 0.00375 ohms
We want to find the temp at which the resistance will double, Let the temperature increase by T °C so
\[1.5\times 2=1.5+0.00375\times T\]
From this you can fine T, can't you?
@alfers101 Do you get this?
yup i am thanks. :D now i can answer this one. thanks
This is a problem that i want to solve but i can't really answer it. It's a sample problem from my book:
The density of a copper is 8.89 is 8.89 g/cm^3 and the ρ=1924μΩ-cm. Determine the length(m) and resistance of 12kg of copper; the cross-section of which in 2.09mm^2.
