Given : resistivity of the conductor = 44 * 10^-8 ohm m. R = 14 ohm Diameter = 1mm Area = πD^2/4 = π/4 * (10^-3)^2 m^2 we know that, length of wire = resistance * area/ resistivity of the conductor =. 14 * π/4 * (10^-6)* 1/44*10^-8 = 14 * (22/7*4 )* 10^-6 *1/44*10^-8 = 14 * 22/28 * 100/44 = 22/2 * 100/44 = 100/4 = 25m
