Stead 500 Ohm 250W Wire Wound Potentiometer Resistor

It is a 250W 500 Ohm wire wound variable potentiometer resistor. Its resistive part is rotary. The wiper in this type is mounted on a shaft and the movement of this shaft will change the length and resistance. Basically it is a variable or adjustable rotary potentiometer . It works as when rotate the wiper then resistance will be vary. A Wire Wound Potentiometer Resistor is a variable or adjustable resistor that can control the electrical resistance of a circuit without interrupting the current flow. It is a hollow circular having three connections screw terminal. The ceramic and the wire wound assembly over it are covered by silicone. A resistive wire is wrapped to form a toroid coil with a wiper that slides along the coil's surface. There are three screw terminal when we rotate the wiper in clock-wise direction  resistance  increases and rotate in anti-clockwise direction resistance decrease . It is constructed with a ceramic core. High voltage and current are frequently required in applications.

Features:
