Purpose:

To measure and plot the characteristic curves for a TN2106 MOSFET in order to better understand field effect transistors and how it can behave as a function of terminal voltages. 

Procedure:

A LabVIEW program measures the drain current for a TN2106 MOSFET while varying the drain source  and gate voltage through a range of values. The LabView program has a for loop nested in a for loop.  The Elvis board provided both gate voltage and drain voltage sources which is synchronized in the program.  Next a TN2106 and a 20kOhm potentiometer are used to build a circuit that varies the brightness of a light bulb.  The transistor switching circuit works as expected and varies the light brightness by changing the drain source voltage.
