SUMMARY
The discussion centers on calculating the minimum distance for a spark to jump based on voltage in a vacuum. The key equation referenced is derived from the concept of dielectric strength, which quantifies the maximum electric field a material can withstand without breaking down. For air, the dielectric strength is approximately 3 million volts per meter (3 MV/m). Therefore, the minimum distance (d) for a spark to jump can be calculated using the formula d = V / (3 MV/m), where V is the voltage applied.
