The electrical breakdown of an insulator occurs when an electric field becomes large enough to ionize the insulator, allowing electrical current to flow; lightning is an example of the electrical breakdown of air. The electrical breakdown of air occurs when the electric field reaches about 3×106 N/C . Estimate the magnitude of the total static charge on your body ?body when you generate a static spark with your fingertip when getting out of your car. Assume a spark gap of 1 mm .

    There is a naturally occurring vertical electric field near the Earth's surface that points toward the ground. In fair weather conditions, in an open ficld, the strength of this electric field is 110.0 N/C. A spherical pollen grain with a radius of 13.0 pum is released from its parent plant by a ight breeze, giving it a net charge of -0.850 fC (where 1 fC -1x 10-15 C). What is the ratio of the magnitudes of the electric force to...

    Question 15 Dielectric breakdown, also known as lightening, occurs in air when the electric field exceeds 3 x 106 V/m. An automobile spark plug consists of two metal conductors separated by a distance of 0.72 mm. What is the minimum potential difference between these conductors that is needed for dielectric breakdown (a spark) in the spark plug, expressed in volts? . Question 16. A charge moves a distance of 1.5 m at an angle of 100° with respect to a...

    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...
