The planck’s constant apparatus functions as a ready-built circuit for the measurement of the photoelectric effect. Ideally used in conjunction with the Edu-Lab Picoammeter. 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 UHF lead is included for connecting the picoammeter to the apparatus.
