The electric chair is a device used for capital punishment through electrocution. The electric chair was conceived in 1881 and first used in 1890. The last person to be executed by electric chair without the choice of an alternative method was Lynda Lyon Block on May 10, 2002, in Alabama. The most recent execution by electric chair was of Nicholas Todd Sutton on February 20, 2020, in Tennessee. The electric current in an electric chair varies, with sources reporting currents ranging from 6 to 20 amps. A current of 5 amps or more can singe flesh, hair, and eyes, and also stop a person's heart.

What You'll Learn
Electric chair amperes range from 6 to 20
The electric chair is a device used for capital punishment through electrocution. The person being executed is strapped to a custom wooden chair and electrocuted via electrodes attached to the head and leg. The electric chair was conceived in 1881 and first used in 1890.
The electric chair is designed to kill, not injure, but the same processes are at work whenever anyone gets an electric shock, whether it is lethal or non-lethal. Electric shocks cause tremendous cell and nerve damage and can scar and change the brain in ways doctors do not yet understand. Survivors of electric shocks can lose short-term memory, suffer pain for years afterward, and experience other post-shock symptoms that can take months to manifest.
It is difficult to explain the range of amperes used in electric chairs. It may be that each state has its own electrocution voltage and current regulations, or perhaps each person requires a different amount of current to be killed.

0.07 ampere can be fatal
The electric chair is a device used for capital punishment through electrocution. The person being executed is strapped to a custom wooden chair and electrocuted via electrodes attached to the head and leg.
While voltage is often believed to be the cause of death by electric shock, it is actually the current forced through the body that is fatal. The internal resistance of the human body between the ears is only 100 ohms, while it is around 500 ohms when measured from finger to toe. The resistance of the skin is greater than the resistance inside the body, so the path of the current is an important factor in determining lethality.
In hot and humid conditions, the body's resistance can drop to about 1000 ohms. In such cases, a current of 0.05 amperes (50 milliamps) can be fatal. When submerged in water, the body's resistance decreases even further to about 150 ohms, and a current exceeding 0.05 amperes (7.5 milliamps) can be fatal.
A current of 0.1 amperes for 2 seconds can be fatal. This is because the heart has very low resistance, and a current of only 0.01 amperes (10 milliamps) is sufficient to cause ventricular fibrillation and cardiac arrest, which can lead to death. Therefore, a current of 0.07 amperes can be fatal, especially if the individual has lower resistance due to environmental factors or if the current takes a path through vital organs.

5+ amperes can singe flesh, hair, eyes
The electric chair is a device used for capital punishment through electrocution. The person is strapped to a custom wooden chair and electrocuted via electrodes attached to the head and leg.
The electric chair was first conceived in 1881 by a Buffalo, New York dentist, Alfred P. Southwick, and was developed over the next decade as a more humane alternative to conventional executions, such as hanging.
However, the electric chair has been the subject of controversy, with some people arguing that it is not a humane method of execution. In some cases, individuals have survived the electric chair, and there have been instances where the voltage was too low to cause death.
Doctors believe that certain individuals have a higher tolerance for high voltage, and that 5+ amperes can singe flesh, hair, and eyes. This raises serious ethical concerns about the use of the electric chair as a method of execution, with some arguing that it constitutes cruel and unusual punishment.

250 to 300 milliamps cause loss of consciousness
The electric chair is a device used for capital punishment through electrocution. The process involves strapping the condemned person to a custom wooden chair and passing an electric current through their body via electrodes attached to the head and leg. The electric current causes death by inducing ventricular fibrillation and cardiac arrest.
The severity of injury or death from electrical shock depends on the amount of electric current and the duration of exposure. While a fraction of an ampere (amp) of electricity passing through the body for a few seconds can be fatal, a much lower current of around 250 to 300 milliamps can cause loss of consciousness. This occurs due to respiratory paralysis, where the muscles that control breathing become paralysed and unable to function.
It is important to note that the specific amount of current required to cause loss of consciousness can vary among individuals. Factors such as the voltage, duration of exposure, and physiological differences between individuals can influence the threshold for loss of consciousness. Additionally, the placement of the electrodes and the path of the electric current through the body can also play a role in the effectiveness of the electric chair.
Historical accounts and scientific studies have questioned the effectiveness and humanity of the electric chair as a method of execution. Some individuals have survived the electric chair, while others have experienced prolonged and painful deaths. Doctors have also observed varying tolerances to high voltages among individuals, further complicating the consistency and predictability of this method of execution.

Electric chair designed to kill, not injure
The electric chair is a device used for capital punishment through electrocution. The device applies 2,000 volts to its occupant, who is strapped to a custom wooden chair and electrocuted via electrodes attached to the head and leg.
The electric chair was conceived in 1881 by Alfred P. Southwick, a dentist from Buffalo, New York, as a more humane alternative to conventional executions, particularly hanging. It was first used in 1890 and became a symbolic figure of capital punishment in the United States.
Despite its intention to provide a quick and painless death, the electric chair has been criticised for causing tremendous cell and nerve damage, as well as scarring and changing the brain in ways doctors don't fully understand. Survivors of electric shocks often experience short-term memory loss, forget multiplication tables, and suffer pain for years afterward.
In addition, there have been several instances where individuals were killed only after being subjected to multiple electric shocks, leading to concerns about the cruelty and unusualness of the punishment. In one case, Willie Francis survived the electric chair in 1946 due to improper setup, only to be returned to the electric chair and executed in 1947.
While the electric chair is designed to kill, not injure, the high voltage it employs can result in unintended consequences, including burning and nerve damage. The specific protocols and outcomes vary, but the electric chair remains a controversial method of execution due to its potential for causing prolonged suffering.

Frequently asked questions
Sources suggest that the amps in an electric chair vary between 6 and 20.
Yes, a current of 5 amps or more is enough to singe flesh, hair, and eyes.
No. Doctors believe that certain people have a better tolerance for voltage than others. In 1982, John Louis Evans received three shocks before he died. Smoke was seen coming from his mouth and leg.
No. Electric shocks cause tremendous cell and nerve damage, scarring and changing the brain in ways doctors don't yet understand. Survivors of non-lethal electric shocks report suffering pain for years afterward.
Yes, but rarely. The last person to be executed by electric chair without the choice of an alternative method was Lynda Lyon Block on May 10, 2002, in Alabama. The most recent execution by electric chair was of Nicholas Todd Sutton on February 20, 2020, in Tennessee.
