1) Suppose that you are measuring an ac exalted voltage by orb gap regularity using orbs delay diameters of 12.5 cm in the divine hurry of 1200 kPa and at orb of 35°C One of the orbs is prepared and the exalted voltage is applied to the other one. Suppose that spark of breakdown occurs delay a utmost disunion of 65 mm betwixt the electrodes in your mass. By using Table 3.3 and Table 3.5 adown (enthralled from your textbook), compute the peak appreciate of the exalted voltage.
