Recreational Vehicle (RV) Technician Practice Test

What symbol represents connected wires in electrical diagrams?

1. S

2. C

3. G

4. J

The correct answer is: S

In electrical diagrams, connected wires are commonly represented by the symbol 'S.' This symbol indicates that the wires are not only connected but also conduct electricity, allowing for the flow of current between the components of the circuit. Using the correct symbols is critical in electrical schematics, as these representations ensure that anyone interpreting the diagram can understand how the system should operate. The 'S' symbol serves to prevent confusion, particularly when multiple wires cross paths; it helps to clarify that these wires are intentionally joined instead of merely crossing without an electrical connection. Understanding these symbols is essential for RV technicians, as accurate diagrams are crucial for troubleshooting and repairing electrical systems effectively.
