If the ACA is repealed, with it will go the protection it offers individuals with preexisting health problems.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.
The spark igniter works very similar to the spark plug in a gasoline engine. The electrical current in the igniter jumps across a gap from the igniter to the base of the burner, creating a 15,000 volts direct current (VDC) spark. This very small spark is sufficient to ignite the gas.
