Correct Answer: should be made of a good conductor like copper with sharp-pointed edges
Solution : The correct option is should be made of a good conductor like copper with sharp-pointed edges.
Ideally, a lightning conductor should be made of a highly conductive material with sharp, pointed edges. Copper and aluminium are commonly used materials for lightning conductors due to their excellent electrical conductivity. These materials allow the lightning's electrical energy to flow easily through the conductor and safely into the ground. The pointed edges of a lightning conductor help create a strong electric field, which encourages the surrounding air to ionize. This ionized air forms a conductive path that facilitates the dissipation of the lightning's energy.
