A rheostat is like an adjustable knob that lets you control the volume on your speakers, but instead of sound, it deals with electrical current. It’s a variable resistor that allows us to manage the flow of electricity in a circuit.
A variable resistor, also known as a potentiometer, is a fundamental electronic component that allows manual control over the amount of resistance in an electric circuit. Its primary function is to regulate the flow of electric current by adjusting the resistance, enabling precise control over voltage, current, or signal levels.
