With qualified Electricians and an apprentice Electrician we are a young business that … WebLarge electric fields ionize the atoms of a dielectric. This means large electric fields create free charges (electrons in this case) that are able to move freely through the material and carry current. This process is called dielectric breakdown because the dielectric transitions from being an insulator to a conductor.
