how arc is formed? please explain in details

Actually the high voltage creates an intense electric field between the small gap. This excites the free electrons present in the air gap and these free electrons start moving at tremendous speed and starts to hit the gas atoms. As a result more electrons are knocked off from the atoms. Thus a Plasma channel is formed which is highly conductive. And the resistance of plasma to the flow of electric current causes the heat of arc.
