How do electrons move in a lightning strike?
Lightning Happens. When the electrical attractive forces between these charge centers gets high enough lightning occurs, which is a flow of electrical current through the air. Thus lightning is a flow of electrical current (flow of electrons) through the air from a negative to a positive charge center.
What happens during a lightning strike?
Typically, when lightning strikes something on the ground, the object that is struck sends a faint channel upward that joins the downward developing flash and creates the connection to the ground. Taller objects are more likely than shorter objects to produce the upward channel.
How is the electric charge generated in lightning?
As the air rises, water vapour cools and forms a cloud. Heavier, negatively charged particles sink to the bottom of the cloud. When the positive and negative charges grow large enough, a giant spark – lightning – occurs between the two charges within the cloud.
What does being struck by lightning feel like?
A jolting, excruciating pain. “My whole body was just stopped—I couldn’t move any more,” Justin recalls. “The pain was … I can’t explain the pain except to say if you’ve ever put your finger in a light socket as a kid, multiply that feeling by a gazillion throughout your entire body.
Is lightning the same as electricity?
Lightning is an electrical current that starts in clouds due to differences in electrical charges between parts of the clouds. There are different types of lightning, including intra-cloud lightning that happens completely inside one cloud.
Where is the safest place in a lightning storm?
A car or other enclosed metal structure is the safest place to be in a thunderstorm. Failing that, a ditch, trench or group of shrubs of uniform height is better than nothing. Keep away from boundary areas between dissimilar terrain (water and land; rock and earth; trees and fields).
What color lightning is the strongest?
What Color Lightning is the Strongest?
- Blue – this color of lightning is an indication that a high precipitation storm is occurring with chances of hail.
- Purple – this color of lightning occurs when there is high humidity in the atmosphere and is typically accompanied by high precipitation.
How does a lightning strike break down the air?
This plane offers little resistance to the power of the lightning strike. Now that there is a huge charge separation the electric field surrounding the cloud starts to break down the air, as in lengthening the space between the electrons and the protons, this process is actually ionizing the air.
How are the electrons in a lightning bolt formed?
Small negatively charged particles called electrons are knocked off some ice and added to other ice as they crash past each other. This separates the positive (+) and negative (-) charges of the cloud. The top of the cloud becomes positively charged while the base of the cloud becomes negatively charged. How is a Lightning Bolt Formed?
Where does the negative charge of lightning come from?
Negative Lightning. As more and more positive charge builds in the upper part of the storm and on the ground beneath the storm, more and more negative charge builds in the lower part of the cloud. The charge separation creates an electric field.
What causes lightning to form in the sky?
One theory proposes that lightning is caused by the loss of electrons from water molecules during cloud formation. Collisions between rising water molecules cause them to lose electrons and become positively charged. Lower portions of the cloud retain the negative electrons creating a charge separation.
