DURING RAIN, WHEN THERE IS THUNDER, CALLING BELL RINGS AUTOMATICALLY. HOW IS IT POSSIBLE?
During rain, as lightening’ jumps speedily, air expands. This louder sound is called as ‘thunder’. The speed of light is more than the sound and hence we see lightening first and then we hear the thunder sound. When it thunders, static electricity, jump speedily to the earth as lightening. When the clouds dash with each other, it gets charged. Counter- clouds, which are in the opposite directions come closer cause power- exchange, through the wind. The rays of light , arising at that time becomes as lightening and jump on the earth through trees.
Sometimes, the static electricity caused by the lightening affects our home electrical equipments and directs them. When this action power increases, there are chances for the equipments to be damaged. Therefore the electrical equipments should be switched off during raining.
