Franklin experimented with lightning to develop the lightning rod to
protect tall and/or secluded structures from being damaged by lightning
strikes. In his experiments, Franklin found that there were two
different kinds of electric charges, he named them positive and
negative charges. A lightning rod is made of highly conductive metal to
attract any lightning strikes near the structure. When struck by
lightning, the charge that the rod receives is sent safely to the
ground by a wire to dissipate the electricity.
