Electrical Injuries
Intensity of the current
The intensity of the current is measured in volts and amperes. Ordinary household current in the United States is 110 to 220 volts. In many other countries, standard household current is 220 volts. A standard electrical outlet in the US is 110 volts, and 220 volts is used for large appliances such as dryers or refrigerators. Anything over 500 volts is considered high voltage. High voltage can jump (arc) through the air anywhere from an inch up to several feet, depending on the voltage. Thus, a person may be injured simply by coming too close to a high-voltage line. High voltage causes more severe injuries than low voltage and is more likely to cause internal damage.
