EARTH
Some electrical systems do not use a return wire, but use another conductor instead. The earth's soil is a conductor and this can be used (hence the name). Metal car bodies are also used as a return wire for automotive circuits and are called 'earth-return' circuits. If the negative supply and one side of each lamp was connected to a metal chassis it would be an 'earth-return' circuit. Earth-return circuits are unsuitable for vessels. |
JUMPER STRUTS
