Our goal for this lab was to calculate the voltage for a resistor, and then build the circuit and compare theoretical with experimental Here's our calculations, for the voltage we calculated 5 volts Here is the experimental value, which is also 5 volts, giving us a percent error of less than .1%. I doubt our experimental value was actually 5V, but I'm assuming the volt meter isn't the most accurate

Mesh Analysis 2 Here is a picture of our schematic.  Here are my calculations the value i got for Ii was -.322 amps and for the voltage i got 4.99 mV Here is the voltage i got for my circuit. it wasn't that far off from my calculated value. I forgot to take a picture for the value of the current, however the value i got was -.52 A. Which was off by a bit %error for V=(4.99-4.10/4.99*100=17.8% error %error for I=(-0.322+.52)/(-.322)*100=52% error I'm assuming the huge percent error in the current was due to not connecting the leads of the DMM to the approritate wires.

For this lab we had to use a BJT in order to light a diode. By connecting a power source to the base of the BJT we allowed the collecter current to lead to the diode. We found the base voltage to be 1.67 V. When we used a 20k resistor the base voltage  was .833V

Dependent Sources and MOSFETs  I didn't take a pic of the DMM with the true value of the resistor, but it's value was 98.9 ohms. Pictured is the diagram of the circuit Here is the table for the V vs I. Our threshold voltage was 13.7 V. The transistor is behaving like a voltage dependent source, because changing the voltage changes the current.  here is the plot of data, with a calculated value for g which is 7.157 Ohms. I calculated this value by finding the slope of the data.                                  Here is a picture of our breadboard                 

Lab day 1 On the first day of lab I did the solderless breadboard lab and another lab that was assigned from the board. Here's the solderless breadboard lab Solderless Breadboards This is the resistance i got when i connected the leads of the DMM to two holes in the same row. The value is .8 ohms which is really low. This operates as a short circuit.  When we connected the two rows of hole son opposite sides of the central channel we noticed that we had a really high resistance, this is because the leads are separated from each other which causes an open circuit. When we connected the leads in two arbitrary holes our DMM had a very large resistance, this is because again, the leads are isolated which causes an open circuit When we connected the leads with a jumper wire between the nodes our DMM read a very low resistance. The reason for this is because this configuration causes a short circuit. For the first part of the lab w...

Nodal Analysis Here is a picture of our circuit diagram.  Our value for v1 was 2.43 V and for v2 was 4.43 .   Here is the voltage we got for v1. We were pretty off our calculated value Here is the V for our v2. Same for this voltage our values were off compared to our prelab values we calculated. Here is a picture of our schematic. I'm assuming we did not calculate our values properly.
