A Rheostat (also known as a variable resistor) is an electrical component to vary the amount of current flowing through the circuit.
A rheostat is a two-terminal variable resistor. Often these are designed to handle much higher voltage and current.
The symbol for a rheostat is a resistor symbol with an arrow diagonally across it.
Rheostats are used in many different applications, from light dimmers to the motor controllers in large industrial machines.
