PIB Constant current limiter 10 µA

To protect the diodes when determining Planck's constant “h” with LEDs (internal photoelectric effect);
Plug-in module for NTL student experiments (STB) constant current regulator 10 µA;
robust plastic housing with transparent base plate, the component is therefore clearly visible and also protected against mechanical damage, the base plate is screwed on with Phillips screws, broken components can therefore be repaired or replaced very quickly and easily, screen-printed lines and circuit symbols create a clearly recognizable circuit diagram of an experimental set-up, robust 4 mm plug pins enable a secure electrical plug-in connection with the metal plates of the plug-in plate
Base plate with two plug pins
Distance between the plug pins: 19 mm
Type: Constant current regulator
Material (upper part): ABS plastic, yellow
Material (plug pins): Brass, nickel-plated
Dimensions: 40 x 40 x 27(41) mm
Mass: 21 g

Several LEDs with different wavelengths are required to carry out the experiment, but it is better to use the entire P9901-PK Planck's “STB” device set
