What are the three factors that affect the severity of an electric shock?

The severity of an electric shock is fundamentally influenced by factors such as the amount of current flowing through the body, the path that current takes through the body, and the duration of the exposure to that current.

The amount of current is critical because it directly correlates with the effects of the shock on the body; different amounts of current can cause various physiological responses, ranging from a mild tickle to potentially fatal heart arrhythmias. The path the current takes is equally important, as certain pathways through the body (such as through the heart or brain) can lead to more severe consequences than others. Lastly, the time factor is significant because prolonged exposure to electric current increases the risk of severe injury or death. As the duration of contact with the electrical source extends, the body's tissues, especially muscles and nerves, face more significant damage, escalating the risk of injuries.

Understanding these factors is crucial for implementing safety measures when working with electrical systems, as it helps professionals evaluate risk and ensure proper precautions are taken to mitigate the dangers associated with electric shock.
