HISTORY:
Benjamin Franklin performed a famous
experiment of FLYING KITE in thunder cloud in the year 1745. Before his
discovery the lightning used to be considered to be "ACT OF GOD". He
also proved that the lightning stroke is because of the discharge of electricity.
He also invented protection of lightning. Lightning rods for fixation on tall
buildings and grounding for their protection from lightning stroke. Thus
Benjamin Franklin is a great scientist in this field.
WHAT IS LIGHTNING?
Lighting is a huge spark which is
due to electrical discharge taking place between the clouds within the same
cloud or between the cloud and earth or ground. Large number of discharge occur
between or within clouds than earth. And enough of them terminate on to the
earth and result in serious hazards. This discharge occurs between
electrically charged regions of a cloud (called intra-cloud lightning or
IC), between two clouds (CC lightning), or between a cloud and the ground (CG
lightning).
