Function of a rheostat
Did you know?
A rheostat is a unit that is considered as a variable resistor. They are a bit like potentiometers. You can change the resistance in a rheostat to control the flow of the current through it. Rheostats are great for controlling the downstream in different devices such as lamps or even transistors. The good thing … See more We all know that to change a current, we should either change the circuit’s resistance or the applied voltage. Rheostat’s function is to change the resistance of the circuit in order to change the circuit’s current. … See more Rheostat’s construction is similar to the potentiometer, but the difference is that it uses two connections instead of three. One of these … See more Rheostats are widely used. One common rheostat uses is in power control devices.
