Dual Relationship

Definition

A dual relationship occurs when an individual has two or more roles or connections with another person, often seen in professional settings where the boundaries between roles may blur. This concept is particularly relevant in analyzing equivalent circuits, as it emphasizes how different perspectives can yield the same electrical behavior, showcasing the interconnectedness of circuit elements under different configurations.
