A resistor with an arrow touching it, marking a variable division of voltage.
Also known as: Pot, Resistor with an arrow
Sometimes confused with: Variable resistor symbol
A resistor with an arrow tapping its body is a potentiometer. The arrow is a wiper contact, and its third terminal is what separates it from a plain variable resistor.
Represents a resistor with a movable contact tapping its length, dividing a voltage between its two ends.
