What three factors determine the severity of injury from contact with electricity?

The severity of injury from contact with electricity is primarily influenced by the route through the body, the amount of current (amperage), and the duration of exposure time.

The route through the body is crucial because different paths can lead to varying degrees of harm. For example, electricity traveling through the heart or brain can result in more severe consequences compared to a path that bypasses vital organs.

Current, measured in amperes, directly correlates to the level of harm. Higher currents increase the risk of serious injuries, including cardiac arrest and tissue damage.

Exposure time is another critical factor; the longer a person is in contact with an electrical source, the greater the potential for injury. Prolonged exposure amplifies the effects of the current and may lead to more severe outcomes.

Together, these elements create a comprehensive view of how electrical injuries manifest, making this choice the most accurate reflection of the factors determining injury severity.
