Mesh Analysis 2 and Time Varying Signals

Mesh Analysis 2

In this lab, we predict what the current I₁ and V₁ for what this circuit will be.

And doing the calculations as shown below:

 We get that:

I₁= -3.2mA

V₁= 5.0184V

After predicting the current and voltage, we collect the resistors and record the actual resistance as shown below:

Thus, taken from the picture, (Except for the 10KΩ is exactly as measured), the circuit for the actual resistors are drawn as shown below: 

After measuring the current I₁ and voltage V₁ and V₂  we get the data below:

Current I₁

% error:  0.9375%

:

 voltage V2

 Voltage V1

% error: 0.964%

For the lecture, mesh analysis is used here in order to find I_B,I_C, and V_o. Thus, by doing the calculations below: 

We get that:

I_B:  .165mA

I_C: 8.25 mA

V_o: 5.175

After the lecture, we went test the response of the circuits by having images of the input and output voltage sketches: 

Summary

In conclusion, we use mesh analysis to find the hidden current and voltage and apply those calculations onto the lecture and the lab. We record the actual measurements and then measured the voltage and current to get the % error between the predicted data and the actual data. Then we also did mesh analysis to find the currents and voltage involving a transistor current. Afterwards, we use the waveform programs to see varying oscillation responses from the circuit.
