the resistance of 100.0cm of constantan wire whose diameter of cross-section is 0.55m is 5ohm
find the resistivity of constantan wire
solve for resistivity. Normally, One does not deal with wire that is that size. 55 cm diameter wire must be pretty heavy, at least one meter of it. I know my hoist could not lift it. It is bigger than the engine in my car.
