How to make a Rheostat


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.

Any type and size of spring you can use. You can find the spring in the hardware stores.
