Best ResponseYou've already chosen the best response.1Cool:D 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 \[1.5\times 2=1.5+0.00375\times T\] or \[3=1.5+0.00375\times T\] From this you can fine T, can't you?

Best ResponseYou've already chosen the best response.0This 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=1924μΩcm. Determine the length(m) and resistance of 12kg of copper; the crosssection of which in 2.09mm^2.
