The Lethal Factor: Amperage, Not Voltage Alone

Contrary to popular belief, it is not the voltage itself that poses the greatest danger to human life, but rather the amount of current flowing through the body. The human body is a complex system, and when it comes into contact with an electrical source, the current becomes the determining factor in the severity of injury or even death.

While voltage is the driving force behind the flow of electricity, it is the amperage, or the amount of current passing through the body, that has the most significant impact on its effects. A small amount of current, as low as 1/10 of an ampere, passing through the body for just 2 seconds can be enough to cause a fatality. It is crucial to understand that even low voltages can be deadly if the current is sufficient to disrupt the body’s normal electrical functions.

When the current exceeds 10 milliamperes, it can paralyze muscles, making it difficult for the victim to let go of the electrical source or move away from it. Currents above 75 milliamperes can cause ventricular fibrillation, a life-threatening condition where the heart’s normal rhythm becomes chaotic, potentially leading to cardiac arrest. At levels of 4 amps or higher, the electrical current can cause heart paralysis and severe burns. These figures highlight the critical nature of even small amounts of current and emphasize the potential dangers of electrical shocks.
