If only two leads are used on a variable resistor, it is called a ?

When a variable resistor is wired with only two leads, it functions as a rheostat. A potentiometer is normally a three-terminal device used as a voltage divider; using just two leads makes it behave like a rheostat, but the standard two-terminal name for this setup is rheostat. The other options don’t describe a two-terminal variable resistor: a toggle switch merely opens or closes a circuit, and a regulator maintains a set voltage or current.
