If the ACA is repealed, with it will go the protection it offers individuals with preexisting health problems. They would again be denied health insurance or subjected to unaffordable insurance premiums.
The rapid transition from a non-conducting to a conductive state produces a brief emission of light and a sharp crack or snapping sound. A spark is created when the applied electric field exceeds the dielectric breakdown strength of the intervening medium.
Spark plug electric discharge. An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.
