St.Elmo’s fire-A natural phenomenon.
Mar 16, 2018
St.Elmo’s fire is one of the many interesting phenomenon connected with lightning.
All matter is made up of particles-positive and negative.
These forces strongly attract each other, so when there is a buildup of negative charge or positive charge on the base of the clouds,electrons move towards the positive charge resulting in a lightning.
Suppose the lightning hits the lightning rod.
The charge should be broken so that the strain is not too high.
The rod lets the free electrons to leak off.
So instead of a lighting strike the charge would leak off in the form of a brush discharge.
the St.Elmo’s fire is commonly observed on ships, aeroplanes.
