What does the symbol at the right typically represent in electrical diagrams?

In electrical diagrams, the symbol for a variable resistor is typically used to represent an adjustable component that allows the resistance value to be changed based on the application. This functionality is crucial in circuits where tuning or control over current flow is needed, such as in volume controls or light dimmers.

A variable resistor often appears as a zigzag line or a line with an arrow crossing it, indicating the adjustment feature. The ability to modify the resistance makes this component versatile for various electronic applications, enabling fine control over the electrical characteristics of a circuit.

This knowledge is fundamental for interpreting schematics and understanding how different components interact within an electrical system. The distinction between fixed and variable resistors is essential, as it defines how adjustments can be made during the operation of electronic devices.
