Dependent sources and MOSFET & Resisters an Ohm's law LAB


Resisters and Ohms Law voltage current characteristic lab:  In this lab we measured several combinations of voltage and current for a resistor and plot the resulting voltage-current characteristic curve measured for the resistor as showen in the below graph and data table. 



We compared two parallel lines on Voltage vs I graph. both lines says that at zero current their voltage is different.





In MOSFET lab a  simple voltage controlled current source is constructed and tested. we built and tested a circuit which acts as a Voltage Controlled Current Source









Graph of the voltage vs current and table is showen in below & above picture. Graph is just a straigh line.

Solderless Breadboards, Open-Circuits and Short-circuits LAB

Using DMM as an ohmmeter we me measured resistance between two holes from node a and node b.. we measured infinate resistance and it was open circuit.

Using DMM as an ohmmeter we me measured resistance between two holes from node a.. we measured 0.6 resistance and it was close circuit.

 Using DMM as an ohmmeter we me measured resistance between two holes from node a and node c. we measured infinate resistance and it was open circuit.

 Using DMM as an ohmmeter we me measured resistance between two holes from node a and node b.. we measured 0.5 resistance and it was close circuit.


Above are our written answers to questions which shows resistance measured with different nodes and characteristic of circuit.

Following are few images of DC Circuit problems done in class
