About Lightning Rods
- A lightning rod is an electrical conductor installed on building tops to divert lightning strikes.
- Lightning prefers the path of least resistance, and the rod’s pointed shape creates a stronger electric field, ionising the air and offering a route for the current to flow.
- The lightning rod is connected to a wire leading to the ground, where the electric charges dissipate.
- This process uses the earth as an infinite source of lower electric potential.
