<b>Lab 2A: Superposition Experiment</b>
|
||||
|
||||
<br><br><i>Note: This part of the lab is just to develop your intuition about
|
||||
superposition. There are no responses that need to be checked.</i>
|
||||
|
||||
<br/><br/>Circuits with multiple sources can be hard to analyze as-is. For example, what is the voltage
|
||||
between the two terminals on the right of Figure 1?

Figure 1. Example multi-source circuit
|
||||
</center>
|
||||
|
||||
<br/><br/>We can use superposition to make the analysis much easier.
|
||||
The circuit in Figure 1 can be decomposed into two separate
|
||||
subcircuits: one involving only the voltage source and one involving only the
|
||||
current source. We'll analyze each circuit separately and combine the
|
||||
results using superposition. Recall that to decompose a circuit for
|
||||
analysis, we'll pick each source in turn and set all the other sources
|
||||
to zero (i.e., voltage sources become short circuits and current
|
||||
sources become open circuits). The circuit above has two sources, so
|
||||
the decomposition produces two subcircuits, as shown in Figure 2.

|

|

<br/>Let's use the DC analysis capability of the schematic tool to see superposition
|
||||
in action. The sliders below control the resistances of R1, R2, R3 and R4 in all
|
||||
the diagrams. As you move the sliders, the schematic tool will adjust the appropriate
|
||||
resistance, perform a DC analysis and display the node voltages on the diagrams. Here's
|
||||
what you want to observe as you play with the sliders:
|
||||
|
||||
<ul style="margin-left:2em;margin-top:1em;margin-right:2em;margin-bottom:1em;">
|
||||
<i>The voltage for a node in Figure 1 is the sum of the voltages for
|
||||
that node in Figures 2(a) and 2(b), just as predicted by
|
||||
superposition. (Note that due to round-off in the display of the
|
||||
voltages, the sum of the displayed voltages in Figure 2 may only be within
|
||||
.01 of the voltages displayed in Figure 1.)</i>
