20 mil volts podem transformar o ar em condutor de eletricidade. Em condições normais, o ar funciona como isolante elétrico, pois suas moléculas possuem elétrons ligados aos átomos. Porém, quando a diferença de potencial (DDP) é muito alta, o campo elétrico se torna intenso o suficiente para arrancar elétrons dessas moléculas. Esse processo é chamado de ionização. Ao serem arrancados, os elétrons livres aceleram devido ao campo elétrico e colidem com outras moléculas do ar, arrancando ainda mai
