the lower surface of the cloud is negatively charged and the upper portion is negatively charged. now when two clouds rubes each other then a huge amount of charge transfer occurs in between the clouds. and if the time constant of this charge transfer is low than a huge amount of current flows between the clouds. this is why we have seen sparking or lightning.

[@manishatumma]

Sir lighting occurs due to the Collision between the clouds or an imbalance occurs between the clouds and ground and the air surrounding Vibrates and creates thunder finally produce an electric discharge which is known as lightning

[@mdhoraira6351]

Moving particles In cloud get ionised and hence carry charge. Whenever charge particles Collide with the Opposite charge particles then lightening happen..... opposite charge particles may moving nearby the earth's surface.

[@buddingscientist170]

whenever charge particles collide with neutral atom under the influence of electric field (which is generated by power line ) then light&sound generate. that is corona

Sir Lighting Over voltage kaliya agar humna Shield wire sa ground may pass kar diya then Lighting Over voltage ka base pay Insulator ko kyue add Kara line (Under 345 KV) may??

[@thexyzme]

Clouds contain negative charges and ground contains positive charges so due to positive negative attraction lighting forms

[@pateltejas9154]

A saperated positive & negative charge of a atom but also bound together called dipole

[@harshashende984]

they are seperated by distance but bound together

[@rushidhangar8695]

Lightning causes the electrons and protons present in molicules of cloud when the two clouds collapse on each other then these electrons and protons also collaps on each other and the large amount of energy will generated this energy will travel toward ground or transmission line in form of surge
