A lightening rod works in protecting one’s home or building by it being placed higher up than the house itself at its highest point. It is placed at the home’s highest point because the highest point is what attracts the lightening first. The lightening travels down the rod by wire to the ground. Once the lightening reaches the ground, it is dissipated harmlessly. The rod acts as a safe conductor for the harmful electricity and damage. The rod will typically have some kind of rubber covering part of it to insulate wire used to hold the rod onto the house.
