Wire-Wound-Rheostat With Enclosure

A rheostat is a variable resistor which is used to control the current flowing in a circuit. Rheostats were often used as power control devices, for example to control light intensity (dimmer), speed of motors, heaters and ovens. Nowadays they are not used for this function anymore. This is because of their relatively low efficiency. In power control applications they are replaced by switching electronics. As a variable resistance they are often used for tuning and calibration in circuits.
