The electric shock. If one amp of current goes through your body and near enough to your heart to disturb your beating, it is surely enough to kill. A human body will die in less than a minute if the current flows through it long enough. Electricity is the flow of electrons through a conductor such as a copper wire. Electric circuits contain elements such as batteries, capacitors, inductors, and switches that control how much of this flow occurs at any given time. Electricity is not dangerous until it enters your body and finds something to do with its many billions of cells. Then it becomes deadly force capable of killing you instantly if it passes enough current through you. In order for an electrical circuit to be safe, each component involved must meet certain safety requirements set by federal law. These components include wires, cables, terminals, buttons, and all other parts of an electrical system. They are required to be properly protected from physical damage and able to withstand normal operating conditions without failure. Failures can occur if excessive heat is produced or not removed in time, if foreign objects are present in critical places, or if electricity reaches levels at which it is still even slightly toxic. The amount of current needed to kill a person varies depending on the type of death caused.
