Doubt regarding current flow during lightening.

In summary, during lightning, the path is not complete or closed, causing the lightning to die after some time. To determine if charges or current are flowing, one can use a lightning rod and observe the high electric current flow during a lightning strike. However, there are also more dangerous methods to determine this.

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 ?Dave
 

1. How does lightning flow through the air?

Lightning is a discharge of electricity that occurs between clouds or between a cloud and the ground. When the charge separation in a cloud becomes too great, the air acts as an insulator and cannot contain the electric potential. This causes a rapid movement of electrons, creating a channel of ionized air molecules that we see as lightning.

2. What is the role of air in lightning conduction?

Air plays a crucial role in the conduction of lightning. As mentioned before, when the electric potential in a cloud becomes too great, the air between the clouds or between the cloud and the ground breaks down and becomes ionized. This allows for the flow of electricity and the formation of a lightning bolt.

3. Is the current flow during lightning constant?

No, the current flow during lightning is not constant. The initial strike of lightning contains a very high current flow, but it quickly decreases. This is due to the resistance of the air and the natural dissipation of the electric potential.

4. Can lightning flow through objects?

Yes, lightning can flow through objects that act as conductors. This includes metal objects such as buildings, trees, and even people. When lightning strikes an object, the current will flow through the conductor and dissipate into the ground.

5. How can we protect ourselves from lightning strikes?

The best way to protect yourself from lightning strikes is to seek shelter in a sturdy building or car. Avoid any open areas, tall objects, and bodies of water. If caught in a storm with no shelter, crouch down on the balls of your feet, keep your feet close together, and cover your ears. Do not lie down on the ground.
