What symbol is used to denote a resistor in electrical diagrams?

The symbol used to represent a resistor in electrical diagrams is depicted as a zigzag line. This symbol is standardized in electrical schematic diagrams, helping engineers and technicians quickly identify components within a circuit. The zigzag pattern reflects the physical properties of a resistor, visually differentiating it from other circuit elements such as conductors or power sources, which are represented by straight lines or other distinct shapes. The usage of this specific symbol facilitates clear communication and understanding among individuals working with electrical systems.
