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 ...

Designers of instruments or control systems often find that component performance limits overall equipment performance in areas such as stability, frequency response, noise, and ESD. This is ...

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 ...

The VRH320 Variable Wire Wound Resistor available from ARCOL Resistors has a wide range of applications for voltage and current adjustment including industrial machinery RPM adjustment, instruments, ...

A resistor is characterized by an always constant resistive value. With the same applied voltage, it will always pass the same amount of current. The potentiometer, on the other hand, is an electronic ...
