Question

What will happen if we use tungsten instead of copper for making conducting wires?

Answer 1

Copper is the least expensive material with suitable conducting ability to permit its use in conducting wires . The conducting ability of a material is indicated by its resistivity. Resistivity of copper is 1.7 x 10^-8 ohm meter and resistivity of tungsten is

5.6 x 10^-8ohm meter. The materials with lower resistivities offer less resistance to the flow of charge; they are better conductors.Here tungsten will offer more resistance if used in wires.
