From various electrical phenomenon that occurs can be found that are caused by the flow of electricity. General wiringPainted metal wire is a copper and aluminium, NA. There are free-electron metal atoms. Do not cling tightly to the atom, thus moving freely. If there is an increase in negative charge cord for 1 free electron is pulled toward a positive charge, positive charge, both to neutral, so the electrons are moving when its missing electron, electric charge is paid, rather than deleted. To achieve the flow of electrons in the wires until the battery plus will be annulled, a neutral. The movement of electrons or electron flow in the wires is called power (Electric Current)Differences between closed-circuit open-circuit1. open circuit is a circuit that electric current cannot flow stop. As a result, the appliances are connected in the circuit could not afford the energy coming out. The cause of the open cycle may be caused by a cable break. Lack of wires. Loose wires. Do not switch on the circuit or electrical appliances in a hurry, tea, etc.2. closed circuit is the circuit that electricity flowing full. TA, load or electrical appliances that are plugged in to the circuit to operate electrical means.
