Doubt regarding current flow during lightening.

Puneeth423

You know current will flow only when the path is complete and closed. During lightning, that doesn't happen. Lightning dies after some time? Its not a complete or closed path. How can you tell that charges are flowing or current is flowing?

This is a good approximation for electronic circuits, but not for charged objects like clouds.

Lightning dies after some time?

As soon as the region around the lightning is discharged.

How can you tell that charges are flowing or current is flowing?

Use a lightning rod, wait for a lightning strike, and you get a high electric current flow inside. There are more dangerous ways, too.

why did you start another thread on the same subject ?

you have already been discussing this in the other thread

did you even bother to look in the other thread where I responded with some diagrams ?
