Determination of Plancks Constant from the LED

Study of Planck’s Constant by Means of LED setup is designed for the experimental determination and study of Planck’s Constant using the current-voltage (I-V) characteristics of a Light Emitting Diode (LED).

The setup allows the study of the dependence of current on temperature at a constant applied voltage. It also provides facilities to draw the I-V characteristics of an LED for the determination of the material constant using a variable voltage source and current meter.
