An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of ...

Moving the position of the slider on this resistor, changes the length of wire in the circuit which changes the resistance. A variable resistor is used in some dimmer switches and volume controls. As ...

I need an adjustable power resistor that can be switched with a resolution of 1Ω. After some thought and web surfing, I bought some 10W wirewounds, which are available in E24 values so that 1, 3, 12 ...
