# Line of sight vs. 90degree shortest distance

#### CruiserFJ62

I am working on a project in which I need to know how high voltage arcing occurs. Will arc travel the line of sight path or will it take the shortest distance which has the 90degree angle? What is the reasoning behind the path that it chooses and does anyone have any websites or articles that discusses the arc path? See the attachment for a better idea.

My understanding is that it takes the path of least resistance, which is not always either straight, the shortest distance...nor a combination.

## 1. What is the difference between line of sight and 90 degree shortest distance?

Line of sight refers to the direct visual path between two points, while 90 degree shortest distance refers to the shortest distance between two points when measured at a 90 degree angle from the ground. In other words, line of sight takes into account any obstacles that may be in the way, while 90 degree shortest distance does not.

## 2. When would you use line of sight versus 90 degree shortest distance?

Line of sight is often used in communication systems, such as radio or satellite transmissions, to ensure there are no obstructions that could interfere with the signal. 90 degree shortest distance may be used in navigation or mapping applications to find the most efficient route between two points.

## 3. How do you calculate line of sight and 90 degree shortest distance?

Line of sight can be calculated using trigonometry, taking into account the height and distance of the two points and any obstacles in between. 90 degree shortest distance can be calculated using the Pythagorean theorem, taking into account the horizontal and vertical distances between the two points.

## 4. What factors can affect line of sight and 90 degree shortest distance?

Line of sight can be affected by atmospheric conditions, such as fog or smog, as well as physical obstructions like buildings or mountains. 90 degree shortest distance can be affected by changes in elevation and terrain, such as hills or valleys.

## 5. Can line of sight and 90 degree shortest distance be the same?

In some cases, they can be the same if there are no obstacles between the two points and the terrain is relatively flat. However, in most cases, they will be different as line of sight takes into account any obstacles while 90 degree shortest distance does not.
