Electrical shock is categorized as high (above 1,000 volts) or low (lower than 100 volts). High voltage injuries cause greater fatalities. However, a fatal injury can be caused by a current as low as 110 volts. In addition to voltage, several other factors determine how much of an electrical shock the body can handle, including: The type of current The pathway of the current through the body The duration of exposure The electrical resistance to the current
