What type of component is represented by a zigzag line on a schematic diagram?

A zigzag line on a schematic diagram is a standard symbol used to represent a resistor. This distinctive shape helps differentiate resistors from other components in an electronic circuit. Resistors are passive components that limit the flow of electric current, playing a crucial role in controlling voltage and current levels within circuits. The zigzag design is a widely recognized convention in electronics to provide clarity and allow for easier identification of components within a schematic, ensuring that engineers and technicians can accurately interpret circuit designs.

Other components, such as capacitors, inductors, and transistors, have their specific symbols, which do not feature a zigzag line, allowing readers to easily distinguish among the different types of components at a glance.
