The resistance offered by a wire of unit length and unit cross-sectional area is called resistivity. For a material irrespective of length and area, the resistivity is constant. It is also called specific resistance of the material. Metals and alloys have low resistivity while insulators have high resistivity. Resistivity of two elements A and B are 1.62 xx 10^(-8) Omega m and 520 xx10^(-8) Omega m respectively. Out of these two, name the element that can be used to make : (i) filament of electric bulb. (ii) wires for electrical transmission lines.
