Mechanism of electrical discharges
The experiments performed by researchers in different countries, notably South Africa, England, Switzerland and the United States, during the last 60 years have greatly advanced our knowledge concerning the mechanism of lightning flashes. However, many pieces of the puzzle pertinent to the mechanism of lightning flashes are still missing and many of the theories put forth as explanation of its mechanism are mainly of qualitative nature. The reason for this slow progress is the impossibility of studying lightning flashes under controlled laboratory conditions. On the other hand, the mechanism of the electric spark, which could be studied under controlled conditions, may guide the researchers in their quest for understanding the mechanism of lightning flashes and creating more advanced theories of the phenomena. After all, it is the observed similarities between the small laboratory sparks and lightning discharges that forced Benjamin Franklin to conclude that lightning flash is a manifestation of electricity. This chapter is devoted to a description of the mechanism of laboratory sparks.
