Why thunderbolts don't travel in straight lines

In summary, electricity travels in straight lines, but lightning takes the shortest path except for the fact that it is the passing of electrons. It is a chain reaction of potential increase.

Why thunderbolts don't travel in straight lines ?
I think the electrical charge likes to move in the shortest path to the Earth and the shortest path must be a straight line !

Well it's really not a "thunder" bolt since thunder is the sound produced from the expanding air. but anyway..

The lighting does take the shortest route except that you're forgetting one thing. The lighting is the passing of electrons from atom to atom. The electrons use the air as their medium of travel in this case, instead of a wire or something you that normally think of with electricity. Basically, whichever way is easiest they will take.. but you must think of it on an atomic level. It's going to be a little jumpy in the paths it takes as the impulse decends downwards.

Also a little fact, the speed it takes to get from top to bottom is not the speed the electrons move. That's the speed of the impulse. The electrons move much more slowly.

It gets much more complex than that too but I think that should be a decent explanation. :smile:

Last night the thunderbolt waked me up, right then this question appeared in my mind.
For such an immediate question this answer is very good and complete.
Thank you

This is still a heavily researched topic in physics. Sporff has it pretty much right from what I know of the subject.

A bolt of lightning, as you probably know, occurs when the difference electrical charge becomes great enough for a spark to jump from one club to another, or from a cloud to the ground. But that is the simplified version. In actuality, there are many pockets of charge differential throughout the air during a thunderstorm. With little pockets of higher and higher potential building up all over the place, when the imbalance between the two charges finally gets high enough, the electrons actually jump from one pocket to another, rather like "connect-the-dots ". If you can see it in slow motion, this actually has a chain reaction effect. Potential drained from one location increases the difference in potentials between that location and its neighbor, causing the neighbor to discharge, and so on.

What sporff told was exactly the answer I was looking for. But now with the last post some more questions are made in my mind which I just ignore them until the time that I know more of the subject :redface:
 

1. Why don't thunderbolts travel in straight lines?

Thunderbolts do not travel in straight lines because they are influenced by the electric fields of surrounding charged particles. As they move through the atmosphere, they interact with air molecules and other charged particles, causing them to change direction and follow a more zigzag path.

2. What causes thunderbolts to zigzag?

Thunderbolts zigzag due to the electric fields of surrounding charged particles. As they move through the atmosphere, they experience the attractive and repulsive forces of these electric fields, causing them to change direction and follow a zigzag path.

3. Can thunderbolts ever travel in straight lines?

While thunderbolts typically do not travel in straight lines, there are rare instances where they can appear to do so. This is usually due to the observer's perspective and the curvature of the Earth. In reality, the thunderbolt is still following a zigzag path, but the curvature of the Earth makes it appear straight from certain vantage points.

4. Do thunderbolts follow the path of least resistance?

No, thunderbolts do not always follow the path of least resistance. While this is a common belief, thunderbolts actually follow the path of least time, meaning they will follow the most efficient route to reach their destination. This may not always be the path of least resistance.

5. Why do thunderbolts sometimes appear to fork into multiple branches?

Thunderbolts can appear to fork into multiple branches due to the complex interactions between the electric fields of surrounding charged particles and the path of the bolt. As the bolt travels through the atmosphere, it may encounter different charged particles and change direction, creating the appearance of multiple branches.
