Which symbol represents a variable resistor?

A variable resistor is shown with the resistor symbol plus an arrow across or touching it. That arrow signals adjustability—the resistance can be changed, like turning a knob. A plain resistor symbol has no arrow, meaning a fixed value. A diode symbol is a triangle and line, used for directing current, not resistance. A motor symbol is typically a circle with an M inside, representing a motor. So the symbol that combines the resistor shape with an adjustable arrow is the one that represents a variable resistor.
