Doubt regarding current flow during lightening.

  1. Oct 1, 2012 #1
    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.

    As soon as the region around the lightning is discharged.

    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 ?
