Potentiometer
PotentiometerA traditional wire potentiometer comprising 1m of 0.56mm diameter Constantan wire on a hardwood base. Connection is by 4mm sockets at either end with contact to the wire being made by a jockey at intermediate points.
Potentiometer 100 Ohm on base
Potentiometer 100 Ohm on baseWire-wound power potentiometer (5 W). The potentiometer is mounted on a solid base with three 4 mm safety sockets. Excellent as variable load resistance, e.g. for smaller solar cells. Withstands up to 220 mA regardless of setting.
