(#220983) {Electric Potential} The spark plugs in an automobile engine produce an electrical spark to ignite the fuel in the engine's combustion chamber. The spark is produced by applying a large voltage across the two electrodes (i.e., small exposed pieces of metal) that are separated by a small air-filled gap. When the electric field in the gap exceeds the electrical breakdown threshold for air, a spark will form across the gap. The gap thickness in most spark plugs run between 0.6 mm and 1.8 mm, and the breakdown threshold for air is 3.0 × 106. Calculate the minimum voltage that must be supplied to the spark plug to guarantee ignition for this full range of gap sizes. (Hint: think about whether a smaller gap or a larger gap will require more voltage to spark, and you want to guarantee that all gap sizes will fire with your "minimum" voltage) m Enter answer here Air Gap Electrodes Image adapted from publicdomainvectors.com Please enter a numerical answer below.
