Why do lightning rods not melt?
Since a lightning strike has a very short duration, the total heat generated during such a strike is not enough to melt metal, but enough to set wood aflame or melt plastic.
Can lightning melt a lightning rod?
Yes, it’s possible. Though, I’m sure the engineers of the Sears Tower took that into account. Catastrophic failure of the rod is pretty straightforward. Lighting is a ton of electrical current, and the rod has some resistance.
Do lightning rods get damaged?
Lightning current will divide to follow every conductive path to ground, and even the divided current can cause damage.
What happens if lightning strikes your lightning rod?
The rod is attached to a copper cable that runs down the side of the building and into the ground. When lightning strikes the rod, the dangerous electrical charge is instantly conducted down the rod, through the wire, and into the ground.

Can a lightning rod be used to attract lightning?
Lightning rods do not attract lightning, but if lightning strikes the rod or very near the rod, it will choose to take the path of least resistance. That is why a single lightning rod may be inadequate for good protection.
Is the tip of a lightning rod sharp?
Furthermore, recent field studies have further shown that the tip of the lightning rod does not need to be sharply pointed as Ben Franklin suggested. Blunt-tipped lightning rods have been found to be more receptive to lightning strikes and thus provide a more likely path of discharge of a charged cloud.
What’s the myth about metal that attracts lightning?
