When the voltage between two charged bodies is large enough, the current will find a path and transfer to a place with low voltage.
However, if there is no conductor in the middle, there is no conduction current.
Air is made up of many molecules, and a single molecule cannot conduct electricity. Atoms combine into molecules by electromagnetic force.
Under the action of high pressure, air will be ionized into ions, which are conductive.
So wires made of ions are formed in the air.
In fact, electric spark is equivalent to a light bulb, and a large amount of current flows through it, generating a large amount of energy.
When an electric spark occurs, firstly, according to Joule's law, heat will be generated. And hot objects emit photons, so there is a flash to see. The violent temperature rise of air causes local gas expansion, which pushes the airflow to fluctuate. This is the sound wave, which is the sound of Tinga, just like the explosion when the gas stove is just lit.
Generally speaking, electric spark is not electricity. Electricity in the traditional sense refers to the flow of electrons, which do not emit light, so we can't see. Luminescence is due to the generation of heat and the violent collision of electrons, which excites photons, just like the principle of laser.
Generally speaking, when an electric spark occurs, a part of electric energy is converted into light energy, heat energy and sound energy.
