#Planck'sConstant #LED # LinearRegression
In this video, I show you how to experimentally determine the Planck constant using LEDs. I have designed a small PCB to make the measurement as convenient as possible. You can also connect an ammeter and, for example, experimentally determine the voltage-current characteristics of the LEDs. The data was analyzed in Excel.
