Dangers of Lightning
A flash of lightning carries a lot of electric energy. When lightning strikes
a building, its tremendous electric energy can set the building on fire or
cause serious damage to its structure. When lightning strikes a tree, it
can burn up the tree and damage it by enormous electric energy.
When the person is hit by lightning during a thunderstorm, then the
electric energy passes through the body of the person due to which the
person gets severe burns and gets killed.
The damage caused to buildings and other tall structures by lightning can
be prevented by installing lightning conductors on them.
Lightning Conductor
Lightning conductor is a device used to protect a building from the effects
of lightning. A lightning conductor is made of a thick strip of
metal (usually of copper). The top end of lightning conductor is pointed
like a sharp spike (or spikes) and it is fixed above the highest point of the
building. From the top of the building, the thick metal strip runs along
the outer wall of the building to the ground. The lower end of metal strip
is joined to a metal plate and buried deep in the ground near the base of
the building.
