What is lightning and how is it formed? What is a lightning bolt? What are the causes of lightning? How is electrical charge distributed through a thunderstorm? Can Lightning’s energy be caught and stored?
The Earth and the atmosphere surrounding it show very interesting electric phenomena.
the earth has negative charge spread with approximately uniform density over its surface. the average surface charge density on the earth is little less than 1 nano coulombs per square metre.
there is a corresponding electric field of about hundred volt per metre in the atmosphere above the earth. field is in the vertically downward direction, when there is raining the air becomes conductive NOt very conductive but little conductive. due to high electric potential around 400 Kvolt in the upper atmosphere make the air conductive and electricity pass through it. the path which is chosen by electricity is where it can pass easily.
send it neutralizes with the Earth surface and in this way lightning occurs. this phenomenon happens in very short duration of time.
today The Lightning energy cannot be stored it can be installed with the help of capacitor battery etc. But it is not yet accomplished scientist are still trying to Store the electrical energy created during lightning. as I have already spoke atmosphere potential upper atmosphere potential is more than 400 kilo volt, so large magnitude of electric current passes through air. its value is around 1800 amperes. so it is not an easy task Play Store electric energy of lightning.
