SUMMARY

The minimum voltage and current required to produce an electric arc in air at a distance of one inch is approximately 10^6 V/m. This value can be scaled based on the distance between the electrodes. For practical applications, understanding the relationship between voltage, current, and distance is crucial for safely generating electric arcs.
