Document Summary
Lightning occurs when a warm front meets a cold front. Lightning sets fires: can be good or bad, depending on what it hits, can aide in rejuvenation of the earth kills off dead plants and trees. When electrical current enters the body, it runs from the point of contact to the point of grounding, following the shortest path: path is from hand to foot or hand to hand. Low-voltage electrocution: occurs while the subject is immersed in water: does not produce electrical burns, ex: electrical appliance (hair dryer) falls into or place in a tub of water. Suppression of the respiratory centers of the brain. When electrical charge is applied to soft tissue, it becomes aerated (puffy) Direct current (d. c. ) is less dangerous than alternating current (a. c. ) Direct current that flows only in on direction, e. g. , derived from a battery (9 volt); sometimes referred to as galvanic current (galvanism: constant.
