They are also called '''potentiometers''' or '''rheostats''' and allow the resistance of the device to be altered by hand. The term ''rheostat'' is usually reserved for higher-powered devices, above about ½ watt. Variable resistors can be inexpensive single-turn types or multi-turn types with a [[helical]] element. Some variable resistors can be fitted with a mechanical display to count the turns.
