Lightning follows the easiest path to discharge its energy. Ionized air during a storm causes the lightning to seek that quickest path. A lightning rod's sole purpose is to attract any lightning in the presence of ionized air to come toward the rod. So for example, lightning will seek the closest metal or tall object (including humans).
When lightning strikes a lightning rod, the rod provides a path of least resistance for the electricity to travel safely to the ground. The lightning is then conducted harmlessly into the earth, minimizing the risk of damage to nearby structures.
A lightning rod is a metal rod or conductor mounted on a building or structure to protect it from lightning strikes. The rod helps to safely conduct the electrical charge from a lightning strike to the ground, reducing the risk of fire or other damage to the building.
If a glass ball on a lightning rod is struck by lightning, it may shatter due to the extreme heat generated by the lightning strike. Additionally, the lightning may travel through the rod to the ground, protecting the building from damage.
A lightning rod is a metal rod mounted on a structure to divert lightning strike away from the building and into the ground, preventing damage from electrical surges. When lightning strikes, the rod provides a path of least resistance for the electrical current to follow, minimizing the risk of fire or other damage.
Lightning is caused by electrons building up, either in the ground or in the clouds. When this electric potential becomes greater than the dielectric strength of the air between ground and clouds, the electrons will flow from one to another in the form of lightning. The dielectric strength of air is directly related to the distance between the two objects of interest. A lightning rod works by being higher than whatever it is meant to protect, so as electrons build up, lightning will strike the rod instead of whatever it is protecting. The lightning rod provides a low impedance path to ground, acting as a drain for the electrical build up. So it attracts lightning by being higher than whatever it is protecting; it also discharges the electrical potential by providing a low impedance path to ground.
Lightning rods are typically made of metal and do not need to be particularly thick to conduct lightning. The most important factor is the material's conductivity, such as copper or aluminum, which allows the lightning to safely pass through the rod and into the ground. The diameter of a lightning rod is usually around ½ inch to 1 inch.

A lightning rod is grounded, meaning it connects to the ground, and the ground is the last place the charge flows to. It is absorbed into the planet Earth.
Any metal that will conduct electricity. Steel works fine, since it is strong. A ground rod driven into the ground and connected to the lightning rod with a wire or cable. The ground rod is usually copper clad (or plated) steel.
The lightning rod enabled people to have a system that prevented their house from being struck by lightning. It is a metal rod that prevented lightning from striking. Instead of striking the target it bounced off the rod and into the ground.
The main way a lightning rod protects a building is by being higher than any other part of the building it maintains a cone of uncharged air over the building. This uncharged air cannot become charged when a thunderstorm passes over as the charges are continuously discharged through the ground wire from the rod to ground. As no charges can be built up within this cone, lightning cannot enter this cone to strike the building. The second way a lightning rod protects a building is that any lightning directly above the building can only strike the tip of the lightning rod itself. The current will then be forced to follow the ground wire from the rod to ground, bypassing the building. However as this current can be in the megaampere range it is necessary to have the complete lightning rod system inspected after any such strike to be sure that parts have not been melted and that the lightning rod is still protecting the building!
The lightning strikes the rod and the rod safely directs the lightning to the ground to keep the house safe.Otherwise,the lightning would discharge onto the roof and likely cause a fire.

A lightning rod is important because it helps protect buildings and structures from being struck by lightning. By providing a path for the electrical discharge of lightning to travel safely into the ground, a lightning rod helps prevent damage and reduce the risk of fire or injury.
