LED current-voltage characteristic
(an approximate determination of Planck's constant)

info

If the experiment is now free, you can start immediately. If you want to book the experiment for a given term, use the booking system.


 Suitable for:

elementary school
demonstration of electroluminescent phenomenon and function of LED
secondary school
in addition: volt-ampere characteristics for different colors of LED, determining of the static and dynamic serial (differential) resistance
university
in addition: relationship between the threshold voltage and the radiated frequency (wavelength) of the light emitted - estimation of Planck's constant
