## Wire Distance Formula

The following formula is used to calculate the Wire Distance.

**Dwire = A * R / p **

- Where Dwire is the Wire Distance (cm)
- A is the cross-sectional area (cm^2)
- R is the resistance (ohms)
- p is the resistivity

## How to Calculate Wire Distance?

The following example problems outline how to calculate Wire Distance.

**Example Problem #1**

- First, determine the cross-sectional area (cm^2).
- The cross-sectional area (cm^2) is calculated to be : 2.5.

- Next, determine the resistance (ohms).
- The resistance (ohms) is measured to be: 6.

- Next, determine the resistivity.
- The resistivity is found to be: 4.

- Finally, calculate the Wire Distance using the formula above:

Dwire = A * R / p

The values given above are inserted into the equation below and the solution is calculated:

Dwire = 2.5 * 6 / 4 = 3.75 (cm)

**Example Problem #2**

The variables needed for this problem are provided below:

cross-sectional area (cm^2) = 3.5

resistance (ohms) = 6

resistivity = 8
