PV2 is connected to the GATE. PV1 is connected to source via a 1K resistor. And DS current is measured as a function of the voltage .

To study n type eMOSFET characteristics.
TODO: Add more details to blog.
The drain current is plotted against the drain-source voltage for various values of GATE voltage ranging from 1.65 volts to 2.0 Volts.
Below 1.65V gate input, the MOSFET does not conduct enough to obtain characteristics
