Edulab China Inside the unit are a caesium antimony cathode, a D/C power supply with a potentiometer to provide a variable retarding voltage to the photoelectric circuit and a digital display showing the retarding voltage. 6 Different coloured lenses are provided to vary the value of ‘f’. A 4mm to lead is included for connecting the picoammeter to the apparatus.
The planck's constant apparatus functions as a ready-built circuit for the measurement of the photoelectric effect.
Ideally used in conjunction with the Edulab China Picoammeter.
