Boltzman Constant Kit
Product Code : JA-PLE-7962
The Boltzman Constant Kit (SKU JA-PLE-7962) determines the Boltzmann constant (k) from the voltage-current characteristics of a semiconductor diode, a quicker and simpler route than methods based on black-body radiation, Wien's displacement law and Stefan's law. This Boltzmann constant kit using diode V-I characteristics provides a digital millivoltmeter, a digital ammeter, a finely adjustable stabilised power supply and silicon and germanium diodes for B.Sc and engineering physics practicals.
Specifications
The kit provides a digital millivoltmeter reading 0-9.99 V across the diode, a digital ammeter reading 0-500 mA, a highly stabilised power supply adjustable in 1 mV steps with a ten-turn potentiometer, and silicon and germanium diodes.
