Although the current flow of a lightning strike occurs only over a short period, the current has an extremely high voltage of some 30 million volts. Lightning is neither a DC or an AC current but best described as a unidirectional massive current impulse of electrons. Lightning strikes are grouped in four categories: direct strikes, side splash, contact<unk> , and ground current. * Direct strike: lightning directly hits the person * Orifice entry: may occur if lightning strike occurs near the head entering eyes, ears and mouth to flow internally * Side splash: lightning jumps from the location of primary strike to a nearby person * Contact<unk> :<unk>  that occurs when a person is touching an object on the pathway of lightning * Ground current: lightning strikes nearby and the current travels through the ground to the person<unk>  may occur by these electrical mechanisms or by secondary blunt trauma as a result of the strike.
