Rheostat, 330 Ω, 0.7 A

An enclosed slide resistor with its resistance element wound on a stable ceramic tube and fitted with three safety sockets, so it works as both a variable resistor and a voltage divider. It can be overloaded by 100% for short periods (up to 4 minutes). The resistance is 330 Ω, rated for 0.7 A and 160 W. It is well suited to low-current experiments, sensor and measurement circuits, input calibration and use as an adjustable load in electronics teaching.
