In summary, a lightning strike is a sudden discharge of electricity between a cloud and the ground or between two clouds. Positive streamers are channels of ionized air that branch out from a positively charged object during a lightning strike. They are formed when an electrical field within a cloud becomes strong enough to ionize air molecules. While positive streamers themselves are not dangerous, they can indicate the presence of a larger, more powerful lightning strike. They can be studied through methods such as high-speed photography, electric field measurements, and computer simulations to better understand lightning behavior.

Lightning strike--->positive streamers

they said the lightning will connect to a positive streamer to "complete" the circuit. When a lightning strikes a man, do human produce positive streamers?

Yes, any conductor in a sufficiently strong electric field will do so, including human body.
 
  • #3


In a strong enough electric field, any material becomes a 'conductor'.
 
  • #4


Yes, but if you take an insulator that breaks down at higher field than air, the field will never get strong enough.
 
  • #5


Yes, when a person is struck by lightning, their body can produce positive streamers. These are created by the ionization of the air surrounding the person's body, which creates a path for the lightning to travel through. However, the majority of the current from the lightning strike will still travel through the person's body, causing potential injury or even death.
 

Related to Lightning strike->positive streamers

What is a lightning strike?

A lightning strike is a sudden discharge of electricity that occurs between a cloud and the ground, or between two clouds.

What are positive streamers in a lightning strike?

Positive streamers are channels of ionized air that branch out from a positively charged object, such as a cloud, during a lightning strike.

How are positive streamers formed during a lightning strike?

Positive streamers are formed when an electrical field within a cloud becomes strong enough to ionize the air molecules, allowing for the flow of electrons and the creation of these branching channels.

Are positive streamers dangerous?

Positive streamers themselves are not dangerous, as they do not carry a significant amount of current. However, they can indicate the presence of a larger, more powerful lightning strike, which can be dangerous to humans and structures.

How can positive streamers be studied?

Positive streamers can be studied through various methods such as high-speed photography, electric field measurements, and computer simulations. Scientists also study the characteristics of positive streamers to better understand lightning behavior and predict lightning strikes.
