## Velocity Factor Formula

The following two example problems outline the steps and information needed to calculate the Velocity Factor.

**VF = 1 / SQRT(k)**

Variables:

- VF is the Velocity Factor ( )
- k is the dielectric constant

## How to Calculate Velocity Factor?

The following steps outline how to calculate the Velocity Factor.

- First, determine the dielectric constant.
- Next, gather the formula from above = VF = 1 / SQRT(k).
- Finally, calculate the Velocity Factor.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **
