Which symbol represents a variable resistor?

Explanation:
The symbol for a variable resistor is a resistor symbol with an arrow crossing it. The arrow shows that the resistance can be adjusted, allowing you to vary the current or voltage in a circuit. This distinguishes it from a fixed resistor, which uses the plain zigzag line with no arrow. The other two symbols—an inductor (a coil) and a capacitor (two parallel plates)—represent entirely different components and have different electrical roles.
