While you are documenting your current network environment, take special note of areas where you are currently experiencing problems. If you stabilize your network before deploying a new operating system, deployment and troubleshooting will be easier, and you can have increased confidence in the upgraded network.
Permittivity, also called electric permittivity, is a constant of proportionality that exists between electric displacement and electric field intensity. This constant is equal to approximately 8.85 x 10-12 farad per meter (F/m) in free space (a vacuum).
This contains the force unit N for Newton and the unit A is the Ampere, the unit of electric current. With the magnetic permeability established, the electric permittivity takes the value given by the relationship where the speed of light c is given by This gives a value of free space permittivity which in practice is often used in the form
