In a typical execution using the electric chair, the prisoner is strapped to a specially built chair. The head and body are shaved to provide better contact with the electrodes that the executioners attaches. Usually three or more people push buttons, but only one is connected to the actual electrical source. That's why the real executioner is unknown.
In three steps they apply 2,000 volts for the first four seconds, then 1,000 volts for the next seven seconds and finally the last step 208 volts for two minutes.
Electrocution produces visibly destructive effects on the body, as the internal organs are burned. The convict usually leaps forward against the restraints when the switch is thrown. The body changes color, swells, and may even catch fire. The prisoner may also defecate, urinate, and vomit blood.
Today the electric chair is used in 11 states. So far, 144 people have died by this method.
