1. The problem statement, all variables and given/known data A 20 ohm platinum wire at 20 C with a temperature coefficient of resistivity of 3.9 x 10 ^-3 /C will have what resistance at 100 C? I know how to answer this in watts and I get 26 W, but for some reason my only options are in ohms. how do i convert Watts to ohms? i looked around and could not find any solid conversion unit. thanks in advance.
