Study Notes
Electrical Symbols and Circuit Diagrams
- Electrical symbols represent components in an electrical circuit.
- Connecting wires are used to connect components in an electrical circuit.
- Wires may be shown crossing over each other in diagrams to indicate that they do not connect, but rather pass over each other without touching.
Wire Materials
- Copper is commonly used to make wires in electrical circuits.
Reference Points
- A reference point in an electrical circuit is a point of zero voltage, used as a reference for measuring voltage at other points in the circuit.
Purpose of Wires
- The purpose of a wire in an electrical circuit is to connect components and allow the flow of electrical current.
Standards for Electrical Symbols
- National and international standards are used to ensure that electrical symbols are consistent and universally understood, allowing for clear communication and accurate representation of electrical circuits.
