If the ACA is repealed, with it will go the protection it offers individuals with preexisting health problems.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.
When the high voltage produced by the ignition system is applied between the center electrode and ground electrode of the spark plug, the insulation between the electrodes breaks down, current flows in the discharge phenomenon, and an electrical spark is generated. This spark energy trigger ignition and combustion in the compressed air-fuel mixture.
