A dot on a ladder diagram indicates what type of connection?

A dot on a ladder diagram represents a terminal or wire connection. In ladder diagrams, which are commonly used in electrical schematics, dots serve as visual indicators to show where two conductors or circuit elements are connected. This is crucial for understanding how the electrical components are interlinked within the circuit.

By representing connections in this way, it allows for easier interpretation of the circuitry and aids in troubleshooting and installation by making it clear to the viewer where connections occur. Understanding the role of these dots helps anyone working with such diagrams to accurately follow and analyze the flow of electricity through the system.
