How do lightning rods prevent lightning strikes from reaching people?

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.

What is Lightning?

  • Lightning is a powerful electrical discharge that occurs when opposite charges build up in the atmosphere and break down the air’s insulating capacity.
  • Lightning strikes occur when electrical charges build up in a cloud beyond the air’s resistance.
