Sliding Rheostat

Sliding Rheostat

Sliding Rheostats are used for starting and controlling the speed of motors, in adjusting generator characteristics, used in controlling storage-battery charging, dimming the lights, and for artificial loads on electrical equipment during tests. Another way to use Rheostats is to limit the current passing through the light bulbs in order to alter brightness. Motor controllers use Sliding Rheostats to control the motor speed by limiting the flow of current through them. Features
