The severity of current passing through the human body is primarily determined by several critical factors: the amount of current flowing, the specific path it takes through the body, and the duration for which the current flows.

The amount of current is crucial because even small currents can be harmful or lethal, depending on the circumstances. For example, a current as low as 10 milliamps can cause involuntary muscle contractions, making it difficult for a person to release their grip on an electric source.

The path that the current takes through the body significantly influences the outcome. Currents passing through vital organs such as the heart or brain are much more dangerous than those flowing through less critical areas. The human body acts as a conductor, and variations in skin resistance, moisture levels, and contact points can alter the actual path and resistance faced by the current.

Duration of the current flow also plays a vital role. The longer the current flows through the body, the greater the potential for tissue damage and harm. Short duration shocks might result in minor injuries, while prolonged exposure can cause severe injuries or fatality.

While the type of electrical source and the voltage can influence risk and safety protocols, they do not directly determine the severity of the current's impact on the human body in
