Tasers have become a popular self-defense tool among law enforcement and civilians alike. However, many people wonder just how powerful these devices are and how much voltage they emit.

If you’re short on time, here’s a quick answer to your question: A typical Taser emits around 50,000 volts of electricity.

In this article, we’ll dive deeper into the world of Tasers and explore the science behind their voltage. We’ll also take a look at some of the safety considerations to keep in mind when using a Taser, and answer some frequently asked questions about these devices.

What Are Tasers and How Do They Work?

Tasers are electroshock weapons used by law enforcement officers to incapacitate a suspect without causing serious injury. They work by delivering an electric shock to the target’s body, causing temporary paralysis and incapacitation. Tasers have become a popular alternative to lethal force in many law enforcement agencies around the world.

The History of Tasers

The first Taser was invented in 1974 by Jack Cover, a NASA researcher. He named the device after a fictional weapon from his favorite childhood book series, Tom Swift. The original Taser used gunpowder to propel two darts attached to wires that delivered an electric shock to the target. Since then, Tasers have undergone significant technological advancements, becoming smaller, more powerful, and more effective at subduing targets.

The Science Behind Tasers

Tasers work by disrupting the body’s electrical signals, causing temporary paralysis and incapacitation. The electric shock delivered by a Taser affects the target’s muscles and nervous system, causing them to contract and spasm. The shock also interferes with the electrical signals sent between the brain and the muscles, making it difficult for the target to move or control their body.

While Tasers are generally considered safe, there have been instances of serious injury or death resulting from their use. This is typically due to factors such as pre-existing medical conditions or improper use of the weapon. Law enforcement agencies are trained to use Tasers responsibly and effectively, with the goal of minimizing harm to both suspects and officers.

How Tasers Work

Tasers use compressed nitrogen to propel two small darts towards the target. The darts are connected to the Taser by thin wires, which deliver an electric shock to the target’s body upon contact. The shock lasts for several seconds, causing temporary paralysis and incapacitation. Tasers typically emit a voltage of around 50,000 volts, but the current is very low, meaning that it is unlikely to cause serious injury or harm to the target.

In addition to their use by law enforcement agencies, Tasers are also available for civilian purchase in many countries. However, their use by non-law enforcement personnel is often regulated, and it is important to understand the laws and regulations governing their use before purchasing or using a Taser.

How Much Voltage Do Tasers Emit?

Tasers, also known as stun guns, are often used by law enforcement to subdue suspects without using lethal force. They work by delivering an electric shock to the body, which causes temporary paralysis and disorientation. But how much voltage do tasers emit?

Typical Voltage of a Taser

The voltage of a taser can vary depending on the model. Most civilian models emit between 50,000 and 80,000 volts, while law enforcement models can emit up to 500,000 volts. However, it’s important to note that voltage is not the only factor that determines the effectiveness of a taser. The duration of the shock, the number of shocks delivered, and the placement of the probes on the body can also affect the outcome.

Why High Voltage is Important for Tasers

High voltage is important for tasers because it allows the electrical current to overcome the body’s natural resistance and reach the muscles. When a taser is fired, the probes pierce the clothing and skin, and the electrical current travels through the body. The high voltage causes the muscles to contract uncontrollably, which renders the suspect temporarily incapacitated. However, high voltage alone is not enough to incapacitate a suspect. The duration of the shock and the number of shocks delivered are also important factors.

How Voltage Affects the Body

When a taser is fired, the electrical current affects the body in several ways. The high voltage causes the muscles to contract, which can result in temporary paralysis. The electrical current can also disrupt the normal functioning of the nervous system, which can cause disorientation and confusion. In rare cases, tasers can cause cardiac arrest or other serious medical complications. However, these cases are relatively rare, and tasers are generally considered safe when used properly.

Are Tasers Safe?

Tasers are non-lethal weapons that are widely used by law enforcement agencies to subdue suspects. However, there have been concerns about their safety and potential risks. In this article, we will explore the safety considerations when using a Taser, the potential risks, and the legal status of Taser use.

Potential Risks of Taser Use

Although Tasers are non-lethal, they can still cause harm to individuals. The most immediate risk of Taser use is the potential for injury from falling after being hit by the stun gun. There have also been cases where individuals with pre-existing medical conditions, such as heart problems, have died after being hit by a Taser.

It is important to note, however, that the risk of injury or death from Taser use is relatively low compared to other forms of force used by law enforcement, such as firearms.

Safety Considerations When Using a Taser

Law enforcement agencies have strict guidelines when it comes to Taser use to minimize the risk of injury or death. Officers are trained to aim for the body’s center mass to reduce the risk of hitting vital organs. They are also trained to use the Taser for a limited amount of time to prevent overexposure to the electric shock.

Additionally, officers are encouraged to avoid using Tasers on individuals who are pregnant, elderly, or have pre-existing medical conditions that may increase the risk of injury or death.

Taser Use and the Law

The use of Tasers by law enforcement is legal in most states and countries. However, there are restrictions on who can use them and under what circumstances. For example, in the United States, only law enforcement officers who have completed Taser training are authorized to use them.

It is also important to note that the use of Tasers must be reasonable and necessary in the given circumstances. The excessive use of force, including the use of a Taser, may result in legal consequences for the officer involved.

FAQs About Tasers

  • What’s the Difference Between a Stun Gun and a Taser?

    While both stun guns and Tasers are considered electroshock weapons, they operate differently. A stun gun requires direct contact with the attacker’s body, and it emits a high-voltage shock that temporarily immobilizes them. On the other hand, a Taser uses probes that are fired from a distance and attach to the attacker’s clothing or skin. The Taser then emits electrical pulses that override the body’s control systems, causing temporary paralysis.

  • Can a Taser Kill You?

    While Tasers are designed to be non-lethal, there have been cases where their use has resulted in death. According to Amnesty International, over 1,000 people have died in the United States after being shocked by a Taser since 2001. However, it’s important to note that the majority of these deaths were attributed to other factors, such as drug use or pre-existing medical conditions.

  • Can You Use a Taser on Someone Who is Wet?

    Yes, you can use a Taser on someone who is wet. In fact, water can actually make the Taser more effective by providing a better conductor for the electrical current.

  • Do Tasers Work on Animals?

    Yes, Tasers can be effective on animals as well as humans. In fact, some police departments use Tasers to subdue aggressive dogs or other animals instead of using lethal force.

  • Can You Buy a Taser for Personal Use?

    The laws regarding the purchase and ownership of Tasers vary by state and country. In some areas, Tasers are legal for personal use by civilians, while in others they are restricted to law enforcement personnel only. It’s important to check the laws in your area before purchasing a Taser.


Tasers are a powerful self-defense tool that have gained popularity in recent years. While the high voltage of these devices may seem intimidating, it’s important to understand how they work and the safety considerations to keep in mind when using them.
