Educational 0-200Ω 1.25A Rheostat - with 4mm Banana Posts

A rheostat is a type of variable resistor used to regulate current or voltage in an electrical circuit by changing its resistance. It operates by changing the position of a slider (drive) on a resistive wire or layer, allowing for a smooth or stepless change in resistance from zero to a maximum value. In practice, a rheostat is a type of potentiometer that uses only two of the three available terminals.How does a rheostat work?Variable Resistance: A rheostat contains a coiled resistance wire or a layer of high-resistance material.Slider (drive): A sliding contact (slider) is located on the wire or layer, which connects to this material.Changing Resistance: Moving the slider allows for a change in the length of the wire through which the current flows, which affects its total resistance.Current Control: By changing the resistance, the current in the circuit can be regulated, consistent with Ohm's Law. Application ExamplesOld Devices: Rheostats were once commonly used in DC motor starters and to regulate the wake-up current in electric machines such as trams.Modern Applications: In some specific applications, such as lighting or fan dimmers, rheostats (or their digital equivalents) still regulate light intensity and speed.Laboratory Applications: In laboratories, rheostats can be used as variable loads for testing devices.Technical data:Resistance: 0- 200Ω
