The electric chair is a device used for carrying out capital punishment through electrocution. It was first introduced in the late 19th century as a more humane alternative to hanging. The chair is designed to deliver a lethal electric shock to the condemned person, causing death quickly. Typically made of wood, the electric chair has restraints to secure the individual during the procedure. Electrodes are placed on the head and leg, and a high-voltage current is applied. While it was once a common method of execution in the United States, its use has declined in favor of other methods, such as lethal injection.
