Understanding the capacity of the human body to withstand electrical voltage is crucial for ensuring safety in various situations. But how many volts can a human survive? The amount of voltage that a human can survive depends on several factors, including the individual’s health and the type of current involved. While it takes very little electricity to kill a person if it directly affects the heart, a constant flow of electricity is more dangerous than a quick shock. Both alternating current (AC) and direct current (DC) electricity pose risks, with approximately 2,700 volts often resulting in death or severe injury, and over 11,000 volts usually leading to fatality.
However, it is important to note that there have been cases where individuals have died from shocks with low volts, while others have survived high voltage shocks. The severity of injury from an electrical shock is also determined by the amount of current and the duration of time the current passes through the body. For example, just 1/10 of an ampere of electricity passing through the body for a mere 2 seconds is enough to cause death. Currents above 10 milliamperes can paralyze muscles, while currents above 75 milliamperes can induce ventricular fibrillation, which can result in death within minutes. Currents above 4 amps can cause heart paralysis and burns.
It is crucial to prioritize electrical safety regardless of the voltage involved.

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.
It is important to note that the severity of injury from electric shock depends not only on the amount of current but also on the duration of exposure. Even a brief encounter with high current can have devastating consequences. That is why electrical safety should never be taken lightly, regardless of the voltage involved. Taking precautions, such as using personal protective equipment and following established safety protocols, is essential in preventing electrical shocks or electrocution.

Understanding the Risks: Heart Fibrillation at 1 Amp
When the body is subjected to an electric shock with a current of 1 amp or more, there is a significant risk of experiencing heart fibrillation, a potentially fatal condition. It takes very little electricity to disrupt the normal electrical activity of the heart and trigger an abnormal rhythm. The severity of the electrical shock’s impact on the heart depends on the amount of current and the duration of exposure.
At currents above 75 milliamperes (mA), the risk of ventricular fibrillation increases. Ventricular fibrillation is characterized by rapid and chaotic electrical activity in the lower chambers of the heart, preventing the heart from effectively pumping blood. Without immediate medical intervention, ventricular fibrillation can quickly lead to cardiac arrest and death within minutes.
Additionally, currents above 4 amps (A) can cause heart paralysis and result in severe burns. The combination of paralysis and burns can have devastating consequences, affecting not only the heart but also other vital organs and tissues. It is important to note that even lower currents, such as 10 milliamperes, can cause muscle paralysis and make it difficult or impossible for an individual to release themselves from the electrical source.
Table: Effects of Electric Shock at Different Current Levels
| Current (Milliamperes) | Effects |
|---|---|
| Below 1 mA | No sensation or perception |
| 1-10 mA | Minor sensation of electrical shock, muscle twitching |
