Lab Day one

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 we had two resistors in series with a voltage supply, we had to calculate the theoretical value of both the resistors' voltage and current.

Our voltage for our power supply was 4V and it's true value was 3.99 V. The values for the resistors were 11.6 ohms for the first and 11.5 for the second resistor, The voltage and current for the first resistor was 1.91 V and .734 A respectively. For the second resistor it's values were 1.93 V and 0.55A . I don't really understand why the current is so different, we used the same resistors and they were in series.

Here is a picture of our values and our circuit



When the resistors were in parallel, we used a 1 V power supply. Our values for the resistors were; for the first resistor it had a voltage of 1.14 and a current of .14 A, for the second resistor it had a voltage of 1.14 and a current of .15 A.

Unfortunately I forgot to take pictures for this part of the lab. However our values fall in line with the theory.

Summing Amp Lab

Image
For this lab we had to design an inverting summing circuit. Our two input resistors, R1 and R2 had resistances of 21.2 Kohm and 21.6 Kohm respectively. Theoretically they should R1=22k and R2=22k. Our output resistor had an theoretical resistance of 10k and an actual resistance of 9.7 k. For this lab we had to keep V1 at 1 V, change the Vb voltage and then measure the output voltage. For the second trial, we had to keep V2 at 1 v, change Va and measure the output voltage again. For our prelab, we calculated that our out resistor voltage should be Vo=-(Va+Vb)(R3/R1) Here's the circuit diagram Heres a picture of our circuit Here's our values for constant Va at 1 V Va=1 vb vo -4 1.38 -2 0.46 -1 0 0 -0.42 1 -0.88 2 -1.35 3 -1.81 5 -2.73  Here's our graph We noticed that the op-amp reached saturation at 1.38V and -2.73 V Here...

Inductor Voltage-Current Relations

Image
For this lab we had a resistor and an inductor in series. We had to measure voltages for both elements and use this information to calculate the current running through inductor. The way we could see if our data was accurate was to use Ohm's law through the resistor. Since both elements are in series the would have the same current. For this lab we had a 1mH inductor a 17.6 ohm resistor. Here's a picture of our circuit Here's our graph window for a sinusoidal input voltage with frequency = 1kHz, amplitude = 2V, and offset = 0V Here's our graph window for a  sinusoidal input voltage with frequency = 2 kHz, amplitude = 2V, and offset = 0V Here's the inductor current we got from the wavegen generator and the one calculated from the pre-lab. Our values are pretty off, and I'm not exactly sure why, I'm assuming our math equation was wrong. Here's the graph When we had a frequency of 2khz we basically got the same graph, I'm assuming ...
