Introduction
The purpose of this lab was to review superposition and how to write spice code for circuit analysis.
For this lab we used a combination of hand calculations and Ltspice to measure the following networks.
Task 1
Here are my hand calculations to find the voltage and current for r1,r2, and r3 using super position.
r1
|
2.1V |
1.4mA
|
| r2 |
.9V
|
.6mA
|
| r3 |
2.4V |
.8mA
|
Here is the Ltspice simulation
Figure 1. LTspice code
Figure 2. Vr1 = 3, Vr2 = .9V, Vr3 = 2.4V
Figure 3. Ir1 = 1.4mA, Ir2 = .6mA, Ir3 = .8mA
5. Discussion
The hand calculations and simulation for task 1 are the same.
