In a series circuit, all components are connected end-to-end to form a single path for current flow. In a parallel circuit, all components are connected across each other with exactly two electrically common nodes with the same voltage across each component. Direct current (DC) occurs when the current flows in one constant direction. It usually comes from batteries, solar cells, or from AC/DC converters. DC is the preferred type of power for electronic devices. Alternating current (AC) occurs when the electric current periodically inverts its direction. Live wires carry the power from the source to a switch or appliance. These wires power the electrical demand or load at various locations throughout your home. These may be light switches, electrical outlets, or junction boxes for light fixtures. The neutral wire carries the electricity back to the power source. It completes the circuit by directing the current to a ground or busbar, normally located at the electrical panel. Once the power is “used” at the demand point, it carries it back to the panel. Safety wire is necessary in areas where a bolt could loosen during vibration. Used properly, it will lock so that the wire remains taut and prevents further movement.
