Polarising filters, slides
Polarising filters, slidesAs 327000, but sold as a pair mounted in 50 x 50 mm slides without glass. 1 pair.
Polarising filters, unmounted
Polarising filters, unmountedUnmounted polarising filters for producing plane-polarised light. These quality filters block the light when positioned at 90 degrees to each other (transmitting only 0.005%).

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.
