Electrical injuryAn electrical injury (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. The injury depends on the density of the current, tissue resistance and duration of contact. Very small currents may be imperceptible or only produce a light tingling sensation.
Harold P. BrownHarold Pitney Brown (September 16, 1857, Janesville, Wisconsin – 1944, Volusia, Florida) was an American electrical engineer and inventor known for his activism in the late 1880s against the use of alternating current (AC) for electric lighting in New York City and around the country (during the "war of the currents").
Alternating currentAlternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket.
Electric chairAn electric chair (also known as electrical- or execution chair) is a specialized device used for execution through electrocution. The condemned prisoner is strapped to a custom wooden chair and electrocuted via electrodes attached to the head and legs. Alfred P. Southwick, a dentist in Buffalo, New York, conceived this execution method in 1881.
Thomas EdisonThomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman known for his work on the incandescent light bulb, the phonograph, electric power distribution and early motion pictures. The merger of the Edison General Electric Company and the competitor Thomson-Houston Electric Company resulted in the formation of General Electric. Edison registered 1,093 patents in the United States.
Ventricular fibrillationVentricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. It is due to disorganized electrical activity. Ventricular fibrillation can cause cardiac arrest and loss of consciousness without pulse. This is followed by sudden cardiac death in the absence of treatment. Ventricular fibrillation is initially found in about 10% of people with cardiac arrest.
Arc lampAn arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc). The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light. It was widely used starting in the 1870s for street and large building lighting until it was superseded by the incandescent light in the early 20th century.
Leyden jarA Leyden jar (or Leiden jar, or archaically, Kleistian jar) is an electrical component that stores a high-voltage electric charge (from an external source) between electrical conductors on the inside and outside of a glassjar. It typically comprises a glass jar with metal foil cemented to the inside and the outside surfaces, and a metal terminal projecting vertically through the jar lid to make contact with the inner foil.
New York (state)New York, also called New York State, is a state located in the Northeastern United States. Bordering New England to its east, Pennsylvania and New Jersey to the south, and Canada to its north, New York extends into both the Atlantic Ocean and the Great Lakes. It is the fourth-most populous state in the United States, with over 20 million residents, and the 27th-largest state by area, with a total area of 54,556 square miles (141,300 km2). New York has a varied geography.FibrillationFibrillation is the rapid, irregular, and unsynchronized contraction of muscle fibers. An important occurrence is with regard to the heart. CardiologyThere are two major classes of cardiac fibrillation: atrial fibrillation and ventricular fibrillation. Atrial fibrillation is an irregular and uncoordinated contraction of the cardiac muscle of atria. It can be a chronic condition, usually treated with anticoagulation and sometimes with conversion to normal sinus rhythm.
Pieter van MusschenbroekPieter van Musschenbroek (14 March 1692 – 19 September 1761) was a Dutch scientist credited with the invention of a pioneering capacitor design in the Leyden jar in 1746. He was a professor in Duisburg, Utrecht, and Leiden, specializing in physics, mathematics, philosophy, medicine, and astronomy.
DeathDeath is the end of an organism's life. It is the irreversible cessation of biological functions that sustain a living organism. Death is inevitable for all living things, as nature's tendency to disorder will cause all living systems to degrade and fail through various causes. The identification of the moment of death presents certain difficulties. A person may experience clinical death that is reversible, resulting in some cases in a near-death experience.
