Open-Type Economy Rheostat, 43mm

This open-type economy rheostat functions as a series resistor or potentiometer, featuring oxidized constantan wire wound on a pipe for effective insulation. The slide wire design allows variable resistance and current adjustment. Three 4 mm socket terminals are provided, and the supports are made from ABS molded plastic with a 43 mm diameter. The unit measures 150 mm in length with a resistance of 1.5 ohms and an 8-amp current carrying capacity. It is suitable for physics and electronics experiments involving resistance, voltage division, and circuit control.
